The dreaded White Screen of Death (WSOD) is one of the most frustrating issues a WordPress site owner can face. Suddenly, your website shows a blank white screen with no error message or clues, leaving visitors unable to access your content. Fortunately, WSOD is usually fixable, and with the right preventative measures, you can avoid it altogether.

This guide explains why WSOD happens and offers practical solutions to keep your WordPress site running smoothly.

What Causes the White Screen of Death?

The WSOD can be triggered by various problems, including:

• Plugin or theme conflicts: A poorly coded or incompatible plugin or theme can cause PHP errors that break your site.

• Exhausted memory limit: WordPress may run out of PHP memory due to heavy plugins or scripts.

• Syntax errors: Manual edits to theme or plugin files with incorrect code can crash the site.

• Server issues: Hosting-related problems or misconfigurations may cause WSOD.

• Corrupted core files: Incomplete or failed updates can damage WordPress core files.

For a detailed list of common WSOD causes, visit the WordPress Codex.

How to Fix the White Screen of Death

1. Enable Debugging to See Errors

Add the following to your wp-config.php file to enable error reporting:

This saves error messages to wp-content/debug.log so you can identify the issue without showing errors to visitors.

2. Increase PHP Memory Limit

Edit your wp-config.php or php.ini file to increase memory. For example:

Contact your hosting provider if you’re unsure how to do this.

3. Deactivate All Plugins

A faulty plugin is often the culprit.

• Access your site via FTP or your hosting file manager.

• Rename the wp-content/plugins folder to something like plugins-old to deactivate all plugins.

• Check if your site loads. If yes, reactivate plugins one by one to find the problematic one.

4. Switch to a Default Theme

Your active theme could be causing WSOD.

• Temporarily rename your active theme folder in wp-content/themes.

• WordPress will revert to a default theme like Twenty Twenty-One.

• If this fixes the problem, investigate your theme files or switch themes.

5. Re-upload Core WordPress Files

Sometimes core files become corrupted.

• Download the latest WordPress version from wordpress.org.

• Extract and upload the wp-admin and wp-includes folders via FTP, replacing existing files.

How to Prevent the White Screen of Death

• Regular Backups: Keep backups to restore your site quickly if something breaks. Plugins like UpdraftPlus make this easy.

• Update Carefully: Always update themes, plugins, and WordPress core after backing up.

• Test Updates in a Staging Environment: Use a staging site to check updates before pushing to live.

• Use Reliable Themes and Plugins: Stick to well-reviewed and regularly maintained extensions.

• Monitor PHP Memory Usage: Adjust hosting plans or optimize your site to prevent memory overload.
