How to Fix the WordPress White Screen of Death

Fixing the WordPress White Screen of Death (WSOD)

The White Screen of Death (WSOD) shows a completely blank page — no error message, no content. It is almost always caused by a plugin conflict, theme error, or PHP memory exhaustion.

Step 1 — Enable WordPress Debug Mode

Add this to wp-config.php (before the "That's all" line):

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

Check wp-content/debug.log for the actual error message.

Step 2 — Deactivate All Plugins

1. Via cPanel File Manager, navigate to wp-content/plugins
2. Rename the plugins folder to plugins_disabled
3. Refresh your site

If the white screen disappears, a plugin was the cause. Rename the folder back to plugins, then deactivate plugins one by one from the WordPress admin to find the culprit.

Step 3 — Switch to a Default Theme

1. In File Manager, go to wp-content/themes
2. Rename your active theme folder (e.g., mytheme → mytheme_backup)
3. WordPress will fall back to a default theme (Twenty Twenty-Four)

If this fixes the issue, your theme has a PHP error.

Step 4 — Increase PHP Memory Limit

Add to wp-config.php:

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

Or add to .htaccess:

php_value memory_limit 256M

Step 5 — Check PHP Version Compatibility

In cPanel → MultiPHP Manager, try switching PHP versions. Some older plugins are not compatible with PHP 8.x — try PHP 7.4 as a temporary fix while you update the plugin.
