How to Fix White Screen of Death in WordPress Quickly

The WordPress white screen of death usually happens due to plugin or theme errors or memory limits. To fix it, disable all plugins and switch to a default theme by renaming folders via FTP or hosting file manager, then increase PHP memory limit in wp-config.php.

Why This Happens

The white screen of death in WordPress happens when PHP code stops running and shows a blank page. This usually occurs because of a plugin or theme causing a fatal error or when the site runs out of memory.

For example, a plugin with a syntax error or incompatible code can break the site.

php

<?php
// Broken plugin code example
function broken_function() {
    echo 'Hello World';
// Missing semicolon causes fatal error

Output

<p><strong>Fatal error:</strong> syntax error, unexpected end of file in /wp-content/plugins/broken-plugin.php on line 4</p>

The Fix

To fix the white screen, first disable all plugins by renaming the plugins folder to plugins_old via FTP or your hosting file manager. Then check if the site loads. If it does, rename the folder back and activate plugins one by one to find the culprit.

Next, switch to a default theme like twentytwentyone by renaming your active theme folder.

Also, increase PHP memory by adding this line to wp-config.php:

php

define('WP_MEMORY_LIMIT', '256M');

Output

Site loads normally with plugins disabled and memory increased.

Prevention

To avoid this error in the future, always keep plugins and themes updated and only install trusted ones. Use a staging site to test updates before applying them live. Enable debugging during development by adding define('WP_DEBUG', true); in wp-config.php to catch errors early.

Regularly back up your site so you can restore it if something breaks.

Related Errors

Other errors similar to the white screen of death include:

• 500 Internal Server Error: Often caused by corrupted .htaccess or PHP errors.
• Memory Exhausted Error: When PHP memory limit is too low.
• Parse Error: Syntax errors in PHP files.

Fixes usually involve checking error logs, disabling plugins/themes, and increasing memory limits.

Key Takeaways

Disable all plugins and switch to a default theme to identify the cause of the white screen.

Increase PHP memory limit in wp-config.php to prevent memory exhaustion errors.

Keep plugins and themes updated and test changes on a staging site before going live.

Enable WP_DEBUG during development to catch errors early.

Regular backups help restore your site quickly if errors occur.
