How to Fix WordPress White Screen of Death (WSOD) via cPanel

The WordPress White Screen of Death (WSOD) means your website shows a completely blank white page with no error message. This usually happens due to a PHP fatal error, a broken plugin, or exhausted memory. This guide walks you through the most common fixes.

Fix 1: Enable Debug Mode to See the Error

1. Open cPanel → File Manager.
2. Navigate to public_html and edit the wp-config.php file.
3. Find the line: define( 'WP_DEBUG', false );
4. Replace it with:

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

5. Save the file and reload your website.
6. If the white screen persists, check the debug log at wp-content/debug.log — this file will contain the actual error message.

Fix 2: Disable All Plugins

A broken plugin is the most common cause of WSOD:

1. In cPanel → File Manager, navigate to wp-content/plugins/.
2. Rename the plugins folder to plugins-off.
3. Reload your website. If it loads, a plugin was the cause.
4. Rename the folder back to plugins.
5. Inside the plugins folder, rename each plugin folder one at a time (add -off to the name) until you find the one causing the issue.
6. Delete or update the problematic plugin.

Fix 3: Switch to a Default Theme

1. Go to cPanel → File Manager → wp-content/themes/.
2. Ensure the default theme folder exists (usually twentytwentyfour or similar).
3. Rename your active theme folder by adding -off to its name.
4. WordPress will automatically fall back to the default theme.
5. If your site loads, the theme was the issue. Update it or contact the theme developer.

Fix 4: Increase PHP Memory Limit

1. Edit wp-config.php in File Manager.
2. Add this line above the /* That's all, stop editing! */ line:

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

3. Save and reload your site.
4. If this fixes the issue but you have a managed hosting plan, you may need to contact support to permanently increase the PHP memory limit.

Fix 5: Replace Core Files

1. Download the latest WordPress zip from wordpress.org.
2. Extract it and upload the wp-admin and wp-includes folders to your server via File Manager or FTP, overwriting the existing folders.
3. This replaces all WordPress core files without affecting your themes, plugins, or uploads.

Important Notes

• Always back up your site before making changes to core files.
• WSOD is almost never a hosting issue — it is almost always a plugin, theme, or code problem.
• After fixing WSOD, set WP_DEBUG back to false in wp-config.php to prevent error messages from showing to visitors.
• If you recently installed or updated something before WSOD appeared, that is almost certainly the cause.

Troubleshooting

• WSOD only on specific pages, not the whole site: A plugin or theme function specific to that page is failing. Check the debug log for the error and search for it online with the plugin/theme name.
• WSOD appears only in WordPress admin, not the frontend: A plugin that runs only in the admin area is causing the error. Disable plugins as described in Fix 2.
• WSOD after a WordPress update: A plugin may not be compatible with the new WordPress version. Disable all plugins and re-enable them one by one. Update each plugin to the latest version before re-enabling.
• WSOD and "allowed memory size exhausted" in debug.log: Your PHP memory limit is too low. Increase it as shown in Fix 4, or contact support to raise the server-side limit.
• Nothing works and debug.log is empty: The error may be at the server level. Check if your PHP version is compatible with WordPress. Contact support with your cPanel username for a server-side investigation.
