Less commonly, damaged WordPress core files may also contribute to the problem. The good news is that many of these problems can be identified and fixed without rebuilding your website.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this guide, we\u2019ll start with the quickest checks you can make, then walk you through each troubleshooting step in detail.<\/p>\n\n\n\n<h2 id=\"h-quick-overview-how-to-fix-the-error-establishing-a-database-connection\" class=\"wp-block-heading\"><strong>Quick overview: How to fix the error establishing a database connection<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If WordPress cannot connect to its database, start with the simplest checks before making changes to your site files or database.

The best approach is to rule out each possibility one at a time.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before making changes to your database or WordPress files, create a recent backup of your website. This gives you a restore point if something goes wrong while troubleshooting.<\/p>\n\n\n\n<h3 id=\"h-1-check-your-database-login-credentials\" class=\"wp-block-heading\"><strong>1. Check your database login credentials<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Incorrect database credentials are one of the first things to check when WordPress cannot connect to its database. This can happen after a site migration, password change or database update.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress stores its database connection details in the <code>wp-config.php<\/code> file. For this step, focus on these three values:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Database name <code>(DB_NAME)<\/code>&nbsp;<\/li>\n\n\n\n<li>Database username <code>(DB_USER)&nbsp;<\/code><\/li>\n\n\n\n<li>Database password <code>(DB_PASSWORD)&nbsp;<\/code><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Open your website\u2019s File Manager and locate the <code>wp-config.php<\/code> file in your WordPress installation folder.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.bluehost.com\/blog\/wp-content\/uploads\/2026\/09\/WordPress-wp-config-php-database-credentials-in-Bluehost-File-Manager.png\" alt=\"WordPress wp-config php database credentials in Bluehost File Manager\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019re using Bluehost, go to Websites \u2192 Manage Site \u2192 Files &amp; Access to open File Manager.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the wp-config.php file, look for these database settings:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code><code>define( 'DB_NAME', 'database_name_here' );&nbsp;\ndefine( 'DB_USER', 'username_here' );&nbsp;\ndefine( 'DB_PASSWORD', 'password_here' );&nbsp;\ndefine( 'DB_HOST', 'localhost' );<\/code><\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Compare the database name and username with the details in your hosting account. Bluehost users can check these under Websites \u2192 Manage Site \u2192 Overview \u2192 Databases. Here, you can also confirm that the database user is linked to the correct database and has permission to access it.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the database name or username is incorrect, update the value carefully and save the file. In case the database password was recently changed, make sure the same password is reflected in <code>wp-config.php<\/code>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reload your website after saving the changes. If the credentials are correct and the error remains, verify the database host setting.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Also read:<\/strong> <a href=\"https:\/\/www.bluehost.com\/blog\/wordpress-find-database\/\">How to find WordPress database?<\/a><\/p>\n\n\n\n<h3 id=\"h-2-check-if-your-database-host-information-is-correct\" class=\"wp-block-heading\"><strong>2. Check if your database host information is correct<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your database credentials are correct but WordPress still cannot connect, check the <code>DB_HOST<\/code> value in your <code>wp-config.php<\/code> file. This tells WordPress where to find the database server.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Look for this line:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code><code>define( 'DB_HOST', 'localhost' );<\/code><\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">For Bluehost-hosted WordPress sites, the database host is typically set to <a href=\"https:\/\/www.bluehost.com\/blog\/wordpress-localhost\/\">localhost<\/a>. If you recently migrated your website or changed its database configuration, confirm that the value has not been altered.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you use another hosting provider, the database host may be different. Check with your host before changing the value.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Update <code>DB_HOST<\/code> only if it is incorrect, save the file and reload your website. If WordPress still cannot connect, check whether the database server itself is available before changing your database or WordPress files.&nbsp;<\/p>\n\n\n\n<h3 id=\"h-3-check-for-database-server-downtime-or-resource-issues\" class=\"wp-block-heading\"><strong>3. Check for database server downtime or resource issues<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your WordPress settings are correct, the problem may be coming from the hosting environment rather than your site.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On shared hosting, database availability can sometimes be affected by temporary server load, maintenance or account-level resource limits. In these situations, a <a href=\"https:\/\/www.bluehost.com\/blog\/how-to-fix-error-establishing-database-connection-wordpress\/\">database connection error<\/a> on shared hosting may appear even when your database credentials and WordPress files are correct.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Check for:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Database reachability:<\/strong> Try opening phpMyAdmin through your hosting account. If you can access your database there, the database service is likely available. If you cannot access it, check with your hosting provider.&nbsp;<\/li>\n\n\n\n<li><strong>Service interruptions:<\/strong> Look for maintenance notices or server-status alerts from your hosting provider.&nbsp;<\/li>\n\n\n\n<li><strong>Resource usage:<\/strong> Review your database usage and account limits in your hosting dashboard.&nbsp;<\/li>\n\n\n\n<li><strong>Sudden errors:<\/strong> If the problem appeared without any recent WordPress or database changes, it may point to a temporary hosting-side issue.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If the database server is available and the error remains, check whether corrupted database tables are preventing WordPress from loading correctly.&nbsp;<\/p>\n\n\n\n<h3 id=\"h-4-repair-your-wordpress-database\" class=\"wp-block-heading\"><strong>4. Repair your WordPress database<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your credentials, database host and server availability are all correct, corrupted database tables could be preventing WordPress from working properly. WordPress includes a built-in repair tool that can check and repair these tables.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before running the repair tool, check both your public website and <code>\/wp-admin\/<\/code>. If the front end shows the connection error while <code>\/wp-admin\/<\/code> reports that one or more database tables are unavailable or need repair, database corruption is a more likely cause.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To use it:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1. Open your <code>wp-config.php<\/code> file.\u00a0<\/p>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">2. Add the following line before the line that says &#8216;That&#8217;s all, stop editing! Happy publishing.&#8217;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code><code>define( 'WP_ALLOW_REPAIR', true );<\/code>\n\/* That's all, stop editing! Happy publishing. *\/<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">3. Save the file and visit:\u00a0https:\/\/[yourdomain].com\/wp-admin\/maint\/repair.php<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">4. Once the page loads, you\u2019ll see two options. Select &#8216;Repair Database&#8217;. WordPress will check your database tables and attempt to repair any problems it finds.\u00a0<\/p>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">You do not need to log in to use the repair page while this setting is enabled. For security, remove the <code>WP_ALLOW_REPAIR<\/code> line from <code>wp-config.php<\/code> once the repair is complete.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reload your website after the repair. If the error remains and it began after a recent database change, restoring a known working backup may be the safer recovery option.&nbsp;<\/p>\n\n\n\n<h3 id=\"h-5-restore-your-wordpress-database-from-a-backup\" class=\"wp-block-heading\"><strong>5. Restore your WordPress database from a backup<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If the error started after a recent database change or repair did not work, <a href=\"https:\/\/www.bluehost.com\/blog\/how-to-restore-wordpress\/\">restore a known working backup<\/a>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use a backup created before the error appeared. Keep in mind that restoring an older database may overwrite newer posts, orders, comments or form submissions.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you have an .sql backup, import it through phpMyAdmin. Bluehost users can access phpMyAdmin from Websites \u2192 Manage Site \u2192 Overview \u2192 phpMyAdmin.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After the restore is complete, reload your website. If the error remains and the credentials, database host and server are all working correctly, corrupted WordPress core files can be checked as a later fallback.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Also read:<\/strong> <a href=\"https:\/\/www.bluehost.com\/help\/article\/import-a-mysql-database-using-phpmyadmin\">How to Import or Export a MySQL Database using phpMyAdmin<\/a>&nbsp;<\/p>\n\n\n\n<h3 id=\"h-6-replace-corrupted-wordpress-core-files\" class=\"wp-block-heading\"><strong>6. Replace corrupted WordPress core files<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress core-file corruption is a less common cause of this error. If you\u2019ve already ruled out incorrect credentials, database host issues, server availability and database corruption, replacing the core files can help identify a broader WordPress file issue. Core files can become damaged after a failed update or security incident.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To replace the core files safely:&nbsp;<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Download a fresh copy of WordPress from WordPress.org. Use the same WordPress version your site is currently running unless you intend to update it.&nbsp;<\/li>\n\n\n\n<li>Unzip the downloaded file.&nbsp;<\/li>\n\n\n\n<li>Open your website files using File Manager, FTP or SFTP.&nbsp;<\/li>\n\n\n\n<li>Replace the existing <code>wp-admin<\/code> and <code>wp-includes<\/code> folders with the fresh copies.&nbsp;<\/li>\n\n\n\n<li>Replace the WordPress core files in the root directory with the new copies.&nbsp;<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Do not delete or replace the existing wp-content folder or <code>wp-config.php<\/code> file. These contain your themes, plugins, uploads and site-specific database settings.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once the files are replaced, reload your website. If the connection error still appears after all of these checks, your hosting provider can help confirm whether a supported hosting-side issue is involved.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Also read:<\/strong> <a href=\"https:\/\/www.bluehost.com\/blog\/how-to-reinstall-wordpress-core-files\/\">How to Reinstall WordPress Core Files Safely &amp; Fix Your Site<\/a>&nbsp;<\/p>\n\n\n\n<h3 id=\"h-7-contact-your-hosting-provider\" class=\"wp-block-heading\"><strong>7. Contact your hosting provider<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If none of the fixes above restore the connection, contact your hosting provider. They can help confirm whether there is a known hosting or database service issue and guide you to the appropriate troubleshooting resources.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Share the error message and the steps you have already tried. This gives the support team useful context and helps avoid repeating basic checks.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once you\u2019ve worked through the fixes, it helps to understand how to prevent the connection failure from happening again.

Common causes include incorrect credentials, an incorrect <code>DB_HOST<\/code>, database server downtime, resource limits or corrupted database tables. Damaged core files are a less common cause.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790177765733\"><strong class=\"schema-faq-question\"><strong>What should I do if my database credentials are correct but WordPress still cannot connect?<\/strong>\u00a0<\/strong> <p class=\"schema-faq-answer\">If your database credentials are correct, verify the <code>DB_HOST<\/code> value in <code>wp-config.php<\/code> and confirm the database server is available. If both are correct, investigate corrupted tables, damaged core files or hosting resource limits.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790177780464\"><strong class=\"schema-faq-question\"><strong>Can a database connection error on shared hosting be temporary?<\/strong><\/strong> <p class=\"schema-faq-answer\">Yes. A database connection error on shared hosting can be temporary if the server is undergoing maintenance, experiencing heavy load or reaching resource limits. If it recurs, ask your hosting provider to investigate.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790177797497\"><strong class=\"schema-faq-question\"><strong>Can plugins or themes cause WordPress database connection errors?<\/strong><\/strong> <p class=\"schema-faq-answer\">Usually, no. Themes and most plugins are not direct causes of this error. If it started after a plugin change, disable that plugin and test your site again. Also check for plugins creating unusually high database activity.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790177798978\"><strong class=\"schema-faq-question\"><strong>Is it safe to use WordPress\u2019s built-in database repair tool?<\/strong><\/strong> <p class=\"schema-faq-answer\">Yes. The repair tool checks and fixes corrupted database tables that can stop WordPress from reading site data correctly.
