WordPress White Screen After Update Fix
What You Are Experiencing
Do any of these sound familiar?
Seeing a wordpress white screen after update is alarming. Your site, once live, is now completely blank, leaving visitors and you with no access. This often indicates a critical error preventing WordPress from loading properly, a common issue after a core update. If your wordpress went white after update, you're experiencing a severe disruption that needs immediate attention. This isn't just a visual glitch; it's a complete system failure.
If any of these match, you are in the right place. For general white screen issues, you might consult our guide on the WordPress White Screen of Death — General Fix, but an update-specific issue often requires a targeted approach.
Root Cause
Why this happens
A wordpress white screen after update typically signals a critical conflict or resource exhaustion. The most common culprits include incompatibilities between the new WordPress core version and your existing plugins or theme. An outdated plugin or theme might not be ready for the updated core, leading to fatal PHP errors that halt script execution before any content can render.
Another frequent cause is an insufficient PHP memory limit. The update process itself, or the new core, might demand more resources than your server is currently allocated, resulting in a blank page. Corrupted core files during the update process, or even an incomplete database update, can also leave your wordpress went white after update.
Sometimes, a PHP version mismatch after the update can also trigger this, as detailed in our guide on the WordPress White Screen After PHP Version Upgrade. These issues prevent WordPress from compiling the page, leaving you with an empty screen.
Try This First
Steps you can take right now
Work through these in order. Each step is safe unless noted otherwise.
Check Your Server Error Logs
The first step is always to look for specific error messages. Access your hosting control panel (cPanel, Plesk, etc.) and locate the server error logs. Alternatively, enable WordPress debugging by editing your wp-config.php file. Look for fatal errors that indicate which file or line of code is causing the problem.
define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', false );
Increase PHP Memory Limit
Insufficient PHP memory is a common cause of a wordpress white screen after update. You can try increasing the memory limit by editing your wp-config.php file, php.ini file, or contacting your hosting provider. Be cautious when editing core files; incorrect changes can worsen the problem.
define('WP_MEMORY_LIMIT', '256M');Disable All Plugins via FTP
Plugin incompatibilities are a frequent culprit when your wordpress went white after update. Using an FTP client (like FileZilla), navigate to wp-content/plugins/. Rename the 'plugins' folder to something like 'plugins_old'. This will deactivate all plugins. If your site returns, reactivate plugins one by one to find the conflict. This step carries no data loss risk.
wp-content/plugins/ (rename to wp-content/plugins_old/)
Switch to a Default Theme via FTP
Similar to plugins, your active theme might be incompatible with the new WordPress core, causing your site completely white after wordpress update. Via FTP, navigate to wp-content/themes/. Rename your currently active theme's folder. WordPress will then automatically revert to a default theme (like Twenty Twenty-Four). If the site loads, your theme is the issue. This step carries no data loss risk.
wp-content/themes/your-active-theme/ (rename folder)
Replace WordPress Core Files
Corrupted or incomplete core files from the update can cause a blank screen. Download a fresh copy of WordPress from wordpress.org. Via FTP, upload all files and folders from the new WordPress package except the wp-content folder and wp-config.php file, overwriting existing files. This refreshes the core without affecting your content or settings. Exercise extreme caution; incorrect file replacement can break your site further.
Download fresh WordPress core (excluding wp-content and wp-config.php)
