WordPress White Screen of Death (WSOD): Causes & Fixes

A White Screen of Death (WSOD) is one of the most frustrating WordPress errors – your site loads as a blank white page with no error message. This can happen to any WordPress site, often without warning.

In this guide, we’ll cover:
✅ Top causes of the WordPress White Screen of Death
✅ Step-by-step troubleshooting & fixes
✅ How to prevent it from happening again

What Causes the WordPress White Screen of Death?

The WSOD occurs when PHP crashes silently, preventing WordPress from loading. Common causes include:

1. Plugin or Theme Conflict (Most Common Cause)

🚨 What happens: A faulty plugin/theme crashes PHP execution.
🔧 How to fix: Disable plugins/theme via FTP or recovery mode.

2. Memory Limit Exhausted

🚨 What happens: PHP runs out of memory (Allowed memory exhausted).
🔧 How to fix: Increase wp-config.php memory limit.

3. Corrupted WordPress Core Files

🚨 What happens: Missing or damaged wp-admin or wp-includes files.
🔧 How to fix: Reinstall WordPress manually.

4. PHP Version Incompatibility

🚨 What happens: Old PHP versions conflict with WordPress/core plugins.
🔧 How to fix: Upgrade to PHP 8.0+ (or downgrade if needed).

5. Database Connection Errors

🚨 What happens: wp-config.php has wrong DB credentials.
🔧 How to fix: Verify database settings.

6. Broken .htaccess File

🚨 What happens: Misconfigured rewrite rules crash the site.
🔧 How to fix: Rename .htaccess to reset it.

How to Fix the White Screen of Death (Step-by-Step)

1. Enable Debugging (Find the Error)

Add to wp-config.php:

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

Check /wp-content/debug.log for errors.

2. Disable Plugins (Manual Method)

Access via FTP/SFTP (FileZilla, Cyberduck)
Go to /wp-content/plugins/
Rename plugins folder to plugins_old
Reload site—if it works, reactivate plugins one by one.

3. Switch to Default Theme

Go to /wp-content/themes/
Rename your current theme (forces WordPress to use Twenty Twenty-Four)

4. Increase PHP Memory Limit

In wp-config.php, add:

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

5. Check Database Connection

Verify in wp-config.php:

define('DB_NAME', 'your_db_name');
define('DB_USER', 'your_db_user');
define('DB_PASSWORD', 'your_db_password');
define('DB_HOST', 'localhost');

6. Reinstall WordPress Core

Download a fresh WordPress.zip
Upload wp-admin and wp-includes folders (keep wp-config.php & wp-content)

7. Check for Corrupted .htaccess

Rename .htaccess to .htaccess_old
WordPress will generate a new one.
