How to Fix the WordPress White Screen of Death
The WordPress “White Screen of Death” (WSOD) is one of the most confusing errors — your site simply shows a blank white screen with no message. This guide shows every working fix used by professionals in 2025 so you can restore your site quickly without guesswork.
1
What Causes the White Screen of Death?
WSOD usually happens due to PHP or plugin conflicts.
Common reasons include:
- Plugin or theme conflict
- PHP memory limit exhausted
- Corrupted WordPress core files
- Error in functions.php
- Outdated PHP version
- Cached pages showing broken output
Now let’s fix it step-by-step.
2
Step 1: Enable WordPress Debug Mode
Debugging reveals the exact error causing the WSOD.
Edit your wp-config.php file and add or modify:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
Now check your debug log here:
/wp-content/debug.log

Step 2: Disable All Plugins
The #1 cause of WSOD is a faulty plugin.
If you can access wp-admin:
- Go to Plugins → Installed Plugins
- Deactivate all
- Enable them one by one to find the faulty plugin
If you CANNOT access wp-admin:
- Open FTP or File Manager
- Rename the folder “plugins” → “plugins_old”
- Refresh your website
If site works → one plugin is broken.

Step 3: Switch to a Default Theme
A broken theme or functions.php file may crash your site.
Switch to a default WordPress theme:
- Twenty Twenty-Four
- Twenty Twenty-Three
If wp-admin is inaccessible:
- Rename your active theme folder
- WordPress will auto-switch to a default theme
Check if the site loads normally.

Step 4: Increase PHP Memory Limit
Low memory = PHP crash = white screen.
Add this to wp-config.php:
define('WP_MEMORY_LIMIT', '256M');
Or increase memory via hosting control panel.

Step 5: Clear WordPress, CDN & Browser Cache
Sometimes you see an old cached blank page.
- Clear plugin cache (LiteSpeed, WP Super Cache, WP Rocket)
- Clear CDN cache (Cloudflare: Purge Everything)
- Clear your browser cache
7
Step 6: Replace WordPress Core Files
Sometimes the core WordPress installation is corrupted.
Download a fresh copy of WordPress from WordPress.org, then:
- Replace the wp-admin folder
- Replace the wp-includes folder
- DO NOT overwrite wp-content or wp-config.php
This restores clean system files.

Step 7: Fix Fatal PHP Errors
Fatal errors instantly cause WSOD.
Check your error log:
- /wp-content/debug.log (WordPress)
- Error Logs in hosting panel
- PHP logs via cPanel or SSH
Common PHP issues:
- Missing semicolon or bracket in functions.php
- Plugin update failure
- PHP version mismatch
