Step-by-Step Tutorial Script

Step 1 — What Is the White Screen of Death?

The White Screen of Death (WSOD) occurs when WordPress encounters a fatal PHP error but can’t display the error message, leaving you with a completely blank page.

Common causes include:

• Plugin conflicts
• Theme issues
• PHP memory exhaustion
• Corrupted WordPress files
• Server configuration problems

Step 2 — Check If It’s the Entire Website

Visit:

• Homepage
• /wp-admin
• Another page or post

If only one page is blank, the issue may be content-specific. If the whole site is blank, continue with the next steps.

Step 3 — Enable WordPress Debug Mode

Open the wp-config.php file and replace:

define('WP_DEBUG', false);

with:

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

Then reload your website.

Open:

/wp-content/debug.log

Look for the last error. It often identifies the faulty plugin, theme, or PHP file.

Step 4 — Increase PHP Memory Limit

Edit wp-config.php and add:

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

If your hosting allows it, this can resolve memory-related crashes.

Step 5 — Disable All Plugins

Using your hosting File Manager or FTP:

Go to:

wp-content/

Rename:

plugins

to:

plugins-old

Reload your website.

• If the site loads, one of your plugins is causing the problem.
• Rename the folder back and activate plugins one at a time until you find the culprit.

Step 6 — Switch to a Default Theme

Go to:

wp-content/themes/

Rename your active theme folder.

If you have a default WordPress theme installed (such as Twenty Twenty-Five), WordPress will activate it automatically.

If the site works, your theme is the issue.

Step 7 — Check File Permissions

Recommended permissions:

• Folders: 755
• Files: 644

Incorrect permissions can prevent WordPress from loading properly.

Step 8 — Reinstall WordPress Core Files

Download a fresh copy of WordPress.

Replace:

• wp-admin
• wp-includes

Do not replace:

• wp-content
• wp-config.php

This fixes corrupted core files without affecting your content.

Step 9 — Check PHP Version

Use a supported PHP version such as 8.2 or 8.3 if your plugins and theme are compatible.

Older PHP versions may cause fatal errors with newer plugins.

Step 10 — Review Recent Changes

Ask yourself:

• Did you install a new plugin?
• Did you update your theme?
• Did you edit PHP files?
• Did you update WordPress?

Undo the most recent change and test again.

Step 11 — Restore a Backup

If you have a recent backup from your hosting provider or backup plugin, restoring it can be the quickest solution.

Step 12 — Contact Your Hosting Provider

If none of the previous steps resolve the issue:

• Ask for server error logs.
• Check whether your account has reached resource limits.
• Confirm that PHP and server settings are working correctly.

Common Causes

• Plugin conflicts
• Broken theme updates
• PHP memory limit reached
• Corrupted WordPress files
• PHP compatibility issues
• Incorrect file permissions
• Failed WordPress updates
• Server resource limits

Prevention Tips

• Keep regular backups.
• Test updates on a staging site before applying them to your live website.
• Update plugins and themes from trusted developers.
• Avoid editing live site files without a backup.
• Monitor PHP errors regularly.
