Review plugin and theme compatibility\u00a0<\/h3>\n\n\n\n<p>After updating, head to your WordPress dashboard and review your active plugins.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Look for error messages or compatibility warnings.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Deactivate and reactivate plugins one at a time if you notice issues.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Update all themes and plugins to their latest\u00a0versions.\u00a0Developers\u00a0often release updates to ensure PHP compatibility.\u00a0<\/li>\n<\/ul>\n\n\n\n<p>If you use a custom or older WordPress theme, test its layout and features carefully. Some may need minor updates to work with the latest PHP version.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-check-your-error-logs\">3. Check your error logs\u00a0<\/h3>\n\n\n\n<p>Your hosting&nbsp;account\u2019s&nbsp;control panel stores detailed logs that capture PHP errors and warnings.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Open your Error Logs section and look for entries like \u201cPHP Fatal Error\u201d or \u201cPHP Warning.\u201d\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Note when these\u00a0appear issues\u00a0starting after your update usually\u00a0indicate\u00a0outdated code or incompatible plugins.\u00a0<\/li>\n<\/ul>\n\n\n\n<p>You can also enable WordPress&nbsp;debug&nbsp;mode to spot hidden issues.

The key is to&nbsp;identify&nbsp;the cause&nbsp;quickly&nbsp;so your WordPress site stays online and stable.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-white-screen-of-death-wsod\">1. White screen of death (WSOD)\u00a0<\/h3>\n\n\n\n<p>This is one of the most common PHP-related issues. It usually occurs when PHP&nbsp;encounters&nbsp;a fatal error that prevents WordPress from loading.&nbsp;<\/p>\n\n\n\n<p>Here\u2019s&nbsp;how to fix it:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Enable WordPress debug mode by adding these lines to your wp-config.php\u00a0file:\u00a0<\/li>\n<\/ul>\n\n\n\n<p>define(&#8216;WP_DEBUG&#8217;, true);&nbsp;define(&#8216;WP_DEBUG_LOG&#8217;, true);&nbsp;define(&#8216;WP_DEBUG_DISPLAY&#8217;, false);&nbsp;<\/p>\n\n\n\n<p>This reveals the exact error causing the blank screen.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Check your error logs in your hosting control panel to\u00a0locate\u00a0the faulty plugin or theme.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Temporarily\u00a0deactivate\u00a0all plugins. If your site loads, reactivate them one by one to\u00a0identify\u00a0the culprit.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If the issue continues, switch to a default WordPress theme (like Twenty\u00a0Twenty-Five) to confirm whether your theme is incompatible with the new PHP version.\u00a0<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-incompatible-plugins\">2. Incompatible plugins\u00a0<\/h3>\n\n\n\n<p>Sometimes, plugins built for older PHP versions trigger errors after an update.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Check for plugin updates in your WordPress dashboard. Developers often release compatibility patches for\u00a0latest\u00a0PHP versions.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If no update is available, reach out to the plugin developer to confirm PHP support.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For critical plugins that have no alternatives, you may temporarily downgrade your PHP version until an updated release becomes available.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Long term, consider switching to alternative plugins that are actively\u00a0maintained\u00a0and compatible with newer PHP versions. This ensures better security,\u00a0performance\u00a0and support.\u00a0<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-missing-php-modules\">3. Missing PHP modules\u00a0<\/h3>\n\n\n\n<p>Certain plugins require specific PHP modules like&nbsp;php-curl,&nbsp;php-mbstring&nbsp;or&nbsp;php-xml. If these modules are missing, your website may show partial functionality or plugin errors.&nbsp;<\/p>\n\n\n\n<p>To resolve this:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Contact your hosting provider\u2019s support team and request installation of the missing modules.\u00a0<a href=\"https:\/\/www.bluehost.com\/contact\">Bluehost\u2019s 24\/7 support<\/a>\u00a0can usually handle this quickly.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If\u00a0you\u2019re\u00a0on a VPS or dedicated server, you can manually install modules using a package manager such as apt or yum (depending on your server\u2019s operating system).\u00a0<\/li>\n<\/ul>\n\n\n\n<p>Fixing PHP errors after an update is usually straightforward once you isolate the problem.

Each major PHP version receives active support for about three years, so plan upgrades before your current version reaches\u00a0end\u00a0of life.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1764219306208\"><strong class=\"schema-faq-question\"><strong>Can updating PHP break my WordPress site?<\/strong>\u00a0<\/strong> <p class=\"schema-faq-answer\">It can, but only if your plugins,\u00a0themes\u00a0or custom code\u00a0aren\u2019t\u00a0compatible with the\u00a0new version.
