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

You open your WordPress site and all you see is a completely blank
white page. No error message. No nothing. Just white.

This is the WordPress White Screen of Death and it's one of the most
frustrating errors a WordPress site owner can face. The good news is
it's almost always fixable, and in most cases you don't need to touch
your host or call a developer.

What Causes the WordPress White Screen of Death

Before fixing it, it helps to understand what's happening. The white
screen usually means PHP hit a fatal error and WordPress couldn't
display anything, not even an error message. Common causes include:

• A bad plugin update or a plugin conflict
• A theme that has a PHP error
• Running out of PHP memory
• A corrupted WordPress core file
• A failed update

The frustrating part is that WordPress shows you nothing by default.
That's the first thing we fix.

Step 1: Enable WordPress Debug Mode

This will make the actual error visible so you know exactly what
you're dealing with.

Connect to your site via FTP or your hosting File Manager and open
wp-config.php. Find this line:

define( 'WP_DEBUG', false );

Change it to:

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

Now reload your site. If there's a PHP error, it will now show on
screen instead of a blank page. Read the error it usually tells you
exactly which file or plugin caused the problem.

Once you've fixed the issue, remember to set WP_DEBUG back to
false before going live again.

Step 2: Deactivate All Plugins

Plugins are the number one cause of the white screen. The fastest way
to test this is to deactivate all of them at once.

Since you can't access your dashboard, do it via FTP:

1. Go to /wp-content/plugins/
2. Rename the entire plugins folder to plugins_old
3. Reload your site

If the white screen disappears, a plugin was the culprit. Now:

1. Rename the folder back to plugins
2. Go to your dashboard and Plugins
3. Reactivate them one by one, reloading after each one
4. When the white screen comes back, you've found the bad plugin

Step 3: Switch to a Default Theme

If disabling plugins didn't fix it, your theme might be the problem.

Via FTP, go to /wp-content/themes/ and rename your active theme
folder. WordPress will automatically fall back to a default theme like
Twenty Twenty-Four.

If the site loads again, your theme has a PHP error. You can either
fix the error in the theme code or switch themes permanently.

This is exactly why I always recommend using a child theme for any
customizations. The parent theme stays untouched and recovers easily.

Step 4: Increase PHP Memory Limit

Sometimes the white screen is caused by WordPress running out of
memory. Add this line to your wp-config.php file just above the
line that says /* That's all, stop editing! */:

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

Save the file and reload. If memory was the issue, your site will
come back immediately.

You can also add this to your .htaccess file if wp-config.php
didn't work:

php_value memory_limit 256M

Step 5: Re-upload WordPress Core Files

If none of the above worked, a core WordPress file may be corrupted.

1. Download the latest version of WordPress from wordpress.org
2. Unzip it
3. Upload the wp-admin and wp-includes folders to your server via FTP, overwriting the existing ones
4. Do NOT touch the wp-content folder that's where your themes, plugins, and uploads live

This replaces any corrupted core files without touching your content.

Step 6: Check Your Hosting Error Logs

If you're still stuck, your hosting control panel has error logs that
show exactly what PHP threw. In cPanel, go to Logs then Error Log.
The last few lines will tell you precisely what failed and on which
line of which file.

Preventing the White Screen in Future

• Always take a backup before updating plugins or themes
• Keep PHP updated to 8.1 or higher
• Use a staging site to test updates before pushing to live
• Don't install plugins you don't actually need

The White Screen of Death sounds scary but it's almost always a
plugin, theme, or memory issue. Work through the steps above in order
and you'll have your site back in minutes.
