However, before diving into each step in detail, let\u2019s first understand what this WordPress error actually means. &nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does \u201cThere has been a critical error on this website\u201d mean?<\/h2>\n\n\n\n<p>The \u201cThere has been a critical error on this website\u201d message appears when WordPress encounters a PHP fatal error that prevents a page from loading properly. Instead of showing a blank screen or exposing technical details, newer versions of WordPress display this general WordPress critical error message to protect sensitive information.<\/p>\n\n\n\n<p>This usually means something has gone wrong in your WordPress core files, theme or one of your installed plugins. As a result, the site may become partially or completely inaccessible until the underlying issue &#8211; often a plugin conflict, theme problem or PHP error &#8211; is resolved.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How does WordPress handle critical errors?<\/h3>\n\n\n\n<p>When a fatal PHP error occurs, WordPress tries to protect your site by:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Displaying a generic message instead of detailed error output<\/li>\n\n\n\n<li>Sending a notification to your site admin email inbox<\/li>\n\n\n\n<li>Activating Recovery Mode, which lets you access the WordPress admin area more safely and troubleshoot the issue without taking down the entire site<\/li>\n<\/ul>\n\n\n\n<p>This system, introduced in WordPress 5.2, helps prevent a full site crash and makes it easier to isolate the specific file, plugin or theme causing the error.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When&nbsp;might you&nbsp;see this error?<\/h3>\n\n\n\n<p>You might see this WordPress critical error after:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Updating WordPress, a theme or a plugin<\/li>\n\n\n\n<li>Installing a new plugin that is incompatible with your setup<\/li>\n\n\n\n<li>Editing a PHP file or custom function with invalid code<\/li>\n\n\n\n<li>Exceeding your PHP memory limit<\/li>\n\n\n\n<li>Migrating your site to a new server or hosting provider<\/li>\n\n\n\n<li>Running into database connection or configuration issues<\/li>\n<\/ul>\n\n\n\n<p>In short, this error is a sign that something in your WordPress site\u2019s code or environment has failed and needs troubleshooting. Next, let\u2019s look at the most common causes behind it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common causes of the WordPress critical error<\/h2>\n\n\n\n<p>A WordPress critical error can result from several issues affecting your site\u2019s files, code or server configuration. Identifying the cause is the first step toward restoring your WordPress website.<\/p>\n\n\n\n<p>1. Plugin conflict or faulty updateMalware injections, incorrect file permissions or web server misconfigurations can also trigger PHP errors. These problems are often harder to spot without checking logs or reviewing recent changes to the site environment.Now that you know what usually causes this issue, the next step is to troubleshoot it safely. Let\u2019s look at how to fix the WordPress critical error step by step.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.bluehost.com\/blog\/troubleshooting-issues-themes-plugins\/\" target=\"_blank\" title=\"WordPress Plugin Issues &amp; Theme Troubleshooting Solutions\">Conflicts between WordPress plugins<\/a> or a faulty update are among the most common reasons for a critical error. If a plugin introduces incompatible code or uses more resources than your site can handle, it may break part or all of your website.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Theme incompatibility or custom theme bug<\/h3>\n\n\n\n<p>Errors in a WordPress theme, especially after updates or custom modifications, can trigger a fatal error. This is common when a theme file contains broken code or conflicts with a plugin or WordPress version.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Corrupted WordPress core files<\/h3>\n\n\n\n<p>Incomplete updates or file corruption in directories like wp-admin or wp-includes can stop your site from loading properly. Core file issues may also appear after a failed update, migration or manual file change.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. PHP version mismatch or deprecated functions<\/h3>\n\n\n\n<p>Running an outdated or unsupported PHP version can cause errors when plugins or themes rely on newer functions. This often happens when your hosting environment and WordPress setup are no longer fully compatible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Insufficient memory or resource limits<\/h3>\n\n\n\n<p>When your site runs out of <a href=\"https:\/\/www.bluehost.com\/blog\/wordpress-memory-limit\/\" target=\"_blank\" title=\"How to Increase WordPress Memory Limit &amp; Fix PHP Errors\">allocated PHP memory<\/a>, it may crash with a WordPress critical error message. Memory issues are more likely on plugin-heavy sites or during updates, backups or other resource-intensive tasks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Database corruption or misconfiguration<\/h3>\n\n\n\n<p>Incorrect database credentials, damaged tables or corrupted data can prevent WordPress from working normally. In some cases, the issue affects only part of the site, while in others it can bring down the entire website.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Server or malware issues<\/h3>\n\n\n\n<p>1. Plugin conflict or faulty updateMalware injections, incorrect file permissions or web server misconfigurations can also trigger PHP errors. These problems are often harder to spot without checking logs or reviewing recent changes to the site environment.Now that you know what usually causes this issue, the next step is to troubleshoot it safely. Let\u2019s look at how to fix the WordPress critical error step by step.<\/p>\n\n\n\n<p>1. Plugin conflict or faulty updateMalware injections, incorrect file permissions or web server misconfigurations can also trigger PHP errors. These problems are often harder to spot without checking logs or reviewing recent changes to the site environment.Now that you know what usually causes this issue, the next step is to troubleshoot it safely. Let\u2019s look at how to fix the WordPress critical error step by step.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to fix the WordPress critical error in 11 steps?<\/h2>\n\n\n\n<p>If your site shows \u201cThere has been a critical error on this website,\u201d start with the safest troubleshooting steps first and move to more advanced fixes only if the issue continues. In most cases, the fastest way to fix a WordPress critical error is to identify the plugin, theme, file or server setting that triggered it and reverse the issue step by step.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Check your admin email for a Recovery Mode link<\/h3>\n\n\n\n<p>When a critical error occurs, WordPress often sends an email to your site admin inbox with the subject line \u201cYour Site is Experiencing a Technical Issue.\u201d<\/p>\n\n\n\n<p>This email usually includes a Recovery Mode link that lets you open the WordPress admin area more safely. From there, you can identify the plugin or theme causing the issue and deactivate it without affecting the rest of the site.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Clear cached data<\/h3>\n\n\n\n<p>Sometimes a cached version of the error page continues to appear even after the issue has been fixed.<\/p>\n\n\n\n<p>Clear your browser cache, plugin cache and any cache managed through your hosting control panel. If your site uses a CDN, purge that cache as well. Then reload your site to check whether the error is still active.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Check the logs to identify the issue<\/h3>\n\n\n\n<p>If the error continues, the next step is to look for clues in your logs.<\/p>\n\n\n\n<p>Open the wp-config.php file in your site\u2019s root directory and add the following code before the line that says \u201cThat\u2019s all, stop editing! Happy publishing.\u201d<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">define( 'WP_DEBUG', true );<br>define( 'WP_DEBUG_LOG', true );<br>define( 'WP_DEBUG_DISPLAY', false );<\/pre>\n\n\n\n<p>This <a href=\"https:\/\/www.bluehost.com\/help\/article\/wp-debug\" target=\"_blank\" title=\"How to Enable WordPress Debug Mode (WP Debugging)\">enables debug mode<\/a>, saves error messages to a log file and hides them from visitors.<\/p>\n\n\n\n<p>After saving the file, reload your site and open \/wp-content\/debug.log. Review the latest entries to find the plugin name, theme file, PHP function or file path linked to the fatal error. You can also check your hosting dashboard for <a href=\"https:\/\/www.bluehost.com\/help\/article\/am-php-errors\" target=\"_blank\" title=\"Discover PHP Error Logs in Your Bluehost Portal\">PHP and server logs<\/a> if they are available.<\/p>\n\n\n\n<p>Once you finish troubleshooting, turn debug mode off again by setting WP_DEBUG to false.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Deactivate plugins to rule out conflicts<\/h3>\n\n\n\n<p>Plugin conflicts are one of the most common causes of a WordPress critical error.<\/p>\n\n\n\n<p>If you can access wp-admin through Recovery Mode, deactivate recently updated or newly installed plugins first. If you cannot access the dashboard, use FTP or File Manager to rename the plugins folder temporarily and test whether the site starts loading again.<\/p>\n\n\n\n<p>If the error disappears, reactivate your plugins one at a time until you find the one causing the issue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Switch to a default WordPress theme<\/h3>\n\n\n\n<p>If the issue points to a theme conflict, use FTP or File Manager to rename your active theme folder inside \/wp-content\/themes\/.<\/p>\n\n\n\n<p>WordPress may then fall back to a default theme such as Twenty Twenty-Five. If the site starts working again, the issue is likely within your theme files or a recent theme update.<\/p>\n\n\n\n<p>If using Bluehost,<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.bluehost.com\/blog\/wp-content\/uploads\/2024\/10\/deactivate-plugins-1024x410.png\" alt=\"Disable plugins in WordPress dashboard to quickly fix a WordPress critical error\"\/><\/figure>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Go to the account manager and select Websites.<\/li>\n\n\n\n<li>Select Manage and go to Plugins.<\/li>\n\n\n\n<li>Deactivate plugins individually.<\/li>\n<\/ul>\n\n\n\n<p><strong>Also read: <\/strong><a href=\"https:\/\/www.bluehost.com\/help\/article\/wordpress-disable-themes-plugins\">How to Disable\/Delete Themes and Plugins in WordPress<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 6: Increase the PHP memory limit<\/h3>\n\n\n\n<p>A low PHP memory limit can trigger fatal errors, especially on plugin-heavy sites or during updates, backups or other resource-intensive tasks.<\/p>\n\n\n\n<p>Open wp-config.php and add:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">define( 'WP_MEMORY_LIMIT', '256M' );<\/pre>\n\n\n\n<p>Save the file and reload your site. You may also be able to change this setting in your hosting control panel depending on your provider.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 7: Replace corrupted WordPress core files<\/h3>\n\n\n\n<p>If <a href=\"https:\/\/www.bluehost.com\/blog\/how-to-reinstall-wordpress-core-files\/\" target=\"_blank\" title=\"How to Reinstall WordPress Core Files Safely &amp; Fix Your Site\">WordPress core files<\/a> were damaged during an update, migration or malware incident, replacing them can help restore normal functionality.<\/p>\n\n\n\n<p>Download the latest version of WordPress from wordpress.org, then upload fresh copies of the wp-admin and wp-includes folders to your site using FTP. This refreshes the core files without changing your wp-content folder or database.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 8: Repair the database if needed<\/h3>\n\n\n\n<p><a href=\"https:\/\/www.bluehost.com\/help\/article\/toubleshooting-common-database-errors\" target=\"_blank\" title=\"Troubleshooting Common Database Errors\">Database corruption<\/a> or configuration issues can also trigger a critical error.<\/p>\n\n\n\n<p>You can inspect your database in phpMyAdmin and repair damaged tables if needed. Another option is to temporarily enable the WordPress repair feature by adding this line to wp-config.php:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">define( 'WP_ALLOW_REPAIR', true );<\/pre>\n\n\n\n<p>Then visit:<\/p>\n\n\n\n<p>[yourdomain].com\/wp-admin\/maint\/repair.php<\/p>\n\n\n\n<p>Once the repair is complete, remove the line from wp-config.php.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 9: Roll back a recent update<\/h3>\n\n\n\n<p>If the error started immediately after a WordPress, plugin or theme update, revert the most recent change first.<\/p>\n\n\n\n<p>Delete or deactivate the updated plugin or theme through FTP or File Manager and reinstall a stable version if needed. If the issue began after a core update, restoring a recent backup is usually safer than manually downgrading WordPress.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 10: Check file permissions and configuration files<\/h3>\n\n\n\n<p>Incorrect file permissions or a broken .htaccess file can stop your site from loading properly.<\/p>\n\n\n\n<p>Standard permissions are usually:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Folders: 755<\/li>\n\n\n\n<li>Files: 644<\/li>\n<\/ul>\n\n\n\n<p>You can also temporarily rename .htaccess and reload the site. If the site loads, generate a new .htaccess file by saving your permalink settings in WordPress once access is restored. Review any .user.ini or PHP configuration files as well if they may be affecting memory or timeout settings.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 11: Scan for malware or server issues<\/h3>\n\n\n\n<p>If none of the steps above work, check for malware, suspicious code injections, server misconfiguration or permission issues. <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Review your security logs from dashboard.<\/li>\n\n\n\n<li>Do a quick malware scan to identify bugs.<\/li>\n\n\n\n<li>Check with your hosting provider for server-level errors that may not appear in WordPress logs.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">What if wp-admin is unavailable?<\/h3>\n\n\n\n<p>If you cannot access wp-admin, you can still troubleshoot the WordPress critical error through FTP or your hosting File Manager. This gives you direct access to your site files so you can disable plugins, switch themes, check debug logs and update configuration files safely.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What to do if the error started after an update or code change<\/h2>\n\n\n\n<p>If the WordPress critical error appeared right after an update or code edit, the timing is a strong clue. In many cases, the fastest way to fix the issue is to reverse the most recent change and test your site again.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Identify what changed most recently<\/h3>\n\n\n\n<p>Start by checking whether the error appeared after:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Updating WordPress<\/li>\n\n\n\n<li>Installing or updating a plugin<\/li>\n\n\n\n<li>Updating or editing your theme<\/li>\n\n\n\n<li>Adding custom PHP code<\/li>\n\n\n\n<li>Changing server or PHP settings<\/li>\n<\/ul>\n\n\n\n<p>If the error started immediately after one of these actions, begin your troubleshooting there.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Roll back the last plugin or theme change<\/h3>\n\n\n\n<p>If you recently installed or updated a plugin or theme, deactivate it first.<\/p>\n\n\n\n<p>If you still have dashboard access, disable the plugin or <a href=\"https:\/\/www.bluehost.com\/help\/article\/switching-wordpress-theme\" target=\"_blank\" title=\"How to Switch WordPress Themes Without Losing Content\">switch the theme<\/a> from wp-admin. If you cannot log in, use FTP or File Manager to rename the plugin or theme folder and test the site again.<\/p>\n\n\n\n<p>If the error disappears, the most recent update or change is likely the cause.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Undo recent code edits<\/h3>\n\n\n\n<p>If you added custom code to functions.php, a custom plugin or another PHP file, remove the last change and reload your site.<\/p>\n\n\n\n<p>Even a small syntax error or incompatible function can trigger a fatal error and cause WordPress to stop loading properly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Check compatibility before restoring the change<\/h3>\n\n\n\n<p>Before reactivating the plugin, theme or code snippet, confirm that it is compatible with your current WordPress version, PHP version and other active tools on your site.<\/p>\n\n\n\n<p>This helps prevent the same WordPress critical error from happening again right away.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Restore a backup if needed<\/h3>\n\n\n\n<p>If you cannot isolate the issue quickly and the error started after a recent update or edit, restoring a recent backup may be the safest option.<\/p>\n\n\n\n<p>Choose a backup taken before the change was made, then test your site carefully before applying updates again.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 6: Reapply changes one at a time<\/h3>\n\n\n\n<p>Once your site is working again, reintroduce updates or custom code one at a time.<\/p>\n\n\n\n<p>This makes it easier to confirm which specific change triggered the error and reduces the risk of breaking the site again.<\/p>\n\n\n\n<p>If the error still remains after these steps, the issue may be tied to your hosting environment or a deeper server-level problem. Next, let\u2019s look at when to contact your hosting provider.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When to contact Bluehost &#8211; Your reliable hosting provider<\/h2>\n\n\n\n<p>If the WordPress critical error still remains after basic troubleshooting, the issue may be tied to your hosting environment rather than WordPress alone.

Use trusted plugins and themes<\/h3>\n\n\n\n<p>Poorly coded or unsupported tools often trigger fatal errors.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Only <a href=\"https:\/\/www.bluehost.com\/help\/article\/wordpress-install-plugins\">install WordPress plugins<\/a> and themes from trusted sources.<\/li>\n\n\n\n<li>Check reviews, last update date and compatibility before installation.<\/li>\n\n\n\n<li>Avoid downloading from third-party or nulled sources, which may contain malware.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. Test changes&nbsp;before going live<\/h3>\n\n\n\n<p>Before applying any updates or code edits to your live site, test the&nbsp;changes. You can do so in a staging environment&nbsp;as mentioned earlier.&nbsp;<\/p>\n\n\n\n<p>This allows you to&nbsp;identify&nbsp;issues without affecting your entire website. Most hosting providers offer one-click staging or cloning tools.&nbsp;<\/p>\n\n\n\n<p><strong>Also read: <\/strong><a href=\"https:\/\/www.bluehost.com\/help\/article\/wordpress-how-to-create-a-staging-site\">How to Create a Staging WordPress Site<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Monitor performance and resource usage<\/h3>\n\n\n\n<p>Regularly review your site\u2019s PHP memory limit and server health:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use your hosting control panel to monitor memory usage, CPU load and error logs.<\/li>\n\n\n\n<li>Increase the PHP memory limit if your site experiences frequent fatal errors or timeouts.<\/li>\n\n\n\n<li>Consider <a href=\"https:\/\/www.bluehost.com\/blog\/when-is-the-right-time-to-upgrade-your-hosting-plan-heres-everything-you-need-to-know\/\" target=\"_blank\" title=\"When is the Right Time to Upgrade Your Hosting Plan? Here's Everything You Need to Know - Bluehost Blog\">upgrading your plan<\/a> if your current hosting doesn\u2019t meet resource needs.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">5. Automate backups and error monitoring<\/h3>\n\n\n\n<p>Backups are your best recovery tool during unexpected issues.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Set up automated backups through your hosting dashboard or a plugin.<\/li>\n\n\n\n<li>Use error monitoring tools like WP Activity Log or Sentry to track PHP errors and debug logs in real time.<\/li>\n<\/ul>\n\n\n\n<p>These measures ensure you can quickly restore your WordPress site if a problem arises.<\/p>\n\n\n\n<p><strong>Read more: <\/strong><a href=\"https:\/\/www.bluehost.com\/help\/article\/how-to-create-a-manual-backup\">How to Create a Manual Backup<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Limit direct edits to core or theme files<\/h3>\n\n\n\n<p>Editing PHP files or core files directly can easily break your WordPress site.<\/p>\n\n\n\n<p>Instead, use:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Child themes for customization<\/li>\n\n\n\n<li>Code snippets plugins for minor code changes<\/li>\n\n\n\n<li>Version control systems (like Git) to track changes safely<\/li>\n<\/ul>\n\n\n\n<p>By following these preventive measures, you\u2019ll minimize the chances of running into another critical error message and maintain a stable, high-performing WordPress website.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Final thoughts<\/h2>\n\n\n\n<p>A WordPress critical error can be alarming, but it\u2019s usually easy to fix. Start by checking your admin email for a recovery link, deactivate any problem plugins or themes and use debug mode to pinpoint the issue. If needed, increase PHP memory or restore a recent backup.<\/p>\n\n\n\n<p>To prevent future hiccups, keep your WordPress, themes and plugins updated, test changes in a staging site and monitor server resources. This is where choosing the right hosting makes a real difference. <\/p>\n\n\n\n<p>With Bluehost WordPress hosting, you\u2019re backed by a platform built specifically for WordPress.

In most cases, the issue is linked to a plugin conflict, theme problem, custom code error, low PHP memory or a corrupted file.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-17758158083841\"><strong class=\"schema-faq-question\"><strong>How do I fix the WordPress critical error?<\/strong><\/strong> <p class=\"schema-faq-answer\">Start with the safest troubleshooting steps first. Check your Recovery Mode email, clear cached data, review the debug log, disable plugins, switch to a default theme and check for file or server issues. If the error started after an update or code change, reverse that change first.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-17758158083842\"><strong class=\"schema-faq-question\"><strong>Can I fix the WordPress critical error without wp-admin access?<\/strong><\/strong> <p class=\"schema-faq-answer\">Yes. If you cannot access wp-admin, you can still troubleshoot the issue using FTP or your hosting File Manager. These tools let you disable plugins, rename your active theme, review debug logs and edit files like wp-config.php or .htaccess directly.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-17758158083843\"><strong class=\"schema-faq-question\"><strong>Why does the WordPress critical error keep coming back?<\/strong><\/strong> <p class=\"schema-faq-answer\">If the error keeps returning, the cause is often an unresolved plugin conflict, recurring theme issue, incompatible code, low server resources or a problem introduced during updates.

In many cases, the error is caused by a plugin, theme or PHP issue rather than malware. However, if the error appears alongside suspicious behavior such as unknown file changes, redirects or unusual admin activity, you should also scan the site for malware or compromised files.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-17758158083845\"><strong class=\"schema-faq-question\"><strong>What should I do if the error started after an update?<\/strong><\/strong> <p class=\"schema-faq-answer\">If the error appeared right after updating WordPress, a plugin or a theme, roll back the most recent change first.
