What Is the WordPress White Screen of Death?
The WordPress White Screen of Death is when your website or your WordPress admin dashboard shows a completely blank white page with no error message at all. It can affect just the frontend of your site, just the backend, or both at the same time.
When you try to fix the WordPress White Screen of Death, the hardest part is that WordPress gives you no clue about what went wrong. The browser simply shows nothing. This happens because of an underlying PHP fatal error that WordPress is hiding from your visitors.
What Causes the WordPress White Screen of Death?
Before you fix the WordPress White Screen of Death, it helps to understand the most common causes:
- A plugin conflict (the most common cause)
- A theme error or an incompatible theme
- Insufficient PHP memory limit
- A corrupted WordPress core file
- A bad WordPress update
- Syntax errors in functions.php or other theme files
Now let us go through every method to fix the WordPress White Screen of Death, one by one.
Method 1: Enable WordPress Debug Mode
The very first step to fix the WordPress White Screen of Death is to turn on debug mode. This replaces the blank white screen with the actual PHP error message so you know exactly what is broken.
Step 1: Connect to your website via FTP or your hosting File Manager.
Step 2: Open the file called wp-config.php in your root WordPress folder.
Step 3: Find this line:
php
define( ‘WP_DEBUG’, false );
Step 4: Replace it with these three lines:
php
define( ‘WP_DEBUG’, true );
define( ‘WP_DEBUG_LOG’, true );
define( ‘WP_DEBUG_DISPLAY’, true );
Step 5: Save the file and reload your website.
Now, instead of a white screen, you should see an actual error message. This message will tell you exactly which plugin, theme, or file is causing the problem. Read it carefully; it usually says something like “Fatal error in /wp-content/plugins/plugin-name/…”
Important: Always turn debug mode OFF after you fix the issue by setting WP_DEBUG back to false.
Method 2: Deactivate All Plugins
Plugin conflicts are the number one reason people need to fix the WordPress White Screen of Death. Deactivating all plugins is the fastest way to confirm this is the cause.
If you can still access your WordPress admin:
Go to Plugins → Installed Plugins, select all plugins, and choose Deactivate from the bulk actions dropdown. Then reload your site.
If your admin is also showing a white screen:
Step 1: Connect to your site via FTP or File Manager.
Step 2: Navigate to wp-content/plugins/.
Step 3: Rename the entire plugins folder to something like plugins_disabled.
Step 4: Reload your website. WordPress will deactivate all plugins automatically since the folder name no longer matches.
Step 5: If your site loads, rename the folder back to plugins. Then re-enter the folder and rename each plugin folder one by one, reloading the site each time until the white screen returns. The last plugin you renamed is the culprit.
Method 3: Switch to a Default WordPress Theme
If disabling plugins did not fix the WordPress White Screen of Death, your active theme is likely the culprit.
If you can access your admin:
Go to Appearance → Themes and activate a default WordPress theme like Twenty Twenty-Four.
If your admin is also blank:
Step 1: Go to wp-content/themes/ via FTP.
Step 2: Rename your active theme’s folder (for example, rename generatepress to generatepress_old).
Step 3: WordPress will automatically fall back to a default theme. Reload your site.
If the white screen disappears, your theme was the cause. Either reinstall the theme cleanly or contact the theme developer.
Using GeneratePress? GeneratePress is one of the most stable and lightweight WordPress themes available. If you are not using it yet, you can get GeneratePress here — it rarely causes conflicts like this.
Method 4: Increase the PHP Memory Limit
A very common reason you need to fix the WordPress White Screen of Death is simply that your site ran out of PHP memory. WordPress needs enough memory to run all your plugins and themes, and if your server limit is too low, it crashes silently with a white screen.
Option A — Edit wp-config.php:
Open wp-config.php and add this line above /* That’s all, stop editing! */:
php
define( ‘WP_MEMORY_LIMIT’, ‘256M’ );
Option B — Edit .htaccess:
Open your .htaccess file (in the root folder) and add:
php_value memory_limit 256M
Option C — Edit php.ini:
If your host allows it, open or create a php.ini file in your root folder and add:
memory_limit = 256M
Save and reload your site. This method fixes the WordPress White Screen of Death in many shared hosting environments where the default memory limit is too low (often just 64M or 128M).
Method 5: Re-upload WordPress Core Files
If you still cannot fix the WordPress White Screen of Death after the above methods, a corrupted WordPress core file may be the issue. Re-uploading fresh core files replaces anything broken.
Step 2: Unzip the file on your computer.
Step 3: Delete the wp-content folder from the unzipped files — you must NOT overwrite this folder as it contains all your plugins, themes, and uploads.
Step 4: Using FTP, upload all remaining files to your root WordPress directory, overwriting the existing files.
Step 5: Reload your website.
This replaces any corrupted core files without touching your content.
Method 6: Check for PHP Version Incompatibility
An outdated or incompatible PHP version is an increasingly common reason to fix the WordPress White Screen of Death in 2026, especially after major WordPress or plugin updates.
Step 1: Log in to your hosting control panel (cPanel, Plesk, etc.).
Step 2: Find the PHP Version or MultiPHP Manager setting.
Step 3: Switch to PHP 8.1 or PHP 8.2 (recommended for WordPress in 2026).
Step 4: Save and reload your website.
If switching PHP versions fixes it, the old version was incompatible with a plugin or theme you were running.
Method 7: Restore From a Backup
If you have tried every method above and still cannot fix the WordPress White Screen of Death, restoring from a recent backup is your safest fallback. Most quality WordPress hosting providers include automatic daily backups.
Log in to your hosting dashboard and look for a Backup or Restore option. Select a backup from before the white screen started and restore it.
This is exactly why regular backups are so important. If your current host does not offer automatic backups, it is time to switch to a host that does. I recommend checking the Best WordPress Hosting 2026 guide to find a reliable hosting provider that includes backups.
Still Getting the White Screen of Death?
If you have gone through every method in this guide and the blank white page is still showing, the issue may be more complex, such as a database corruption, a server misconfiguration, or a severely broken installation that needs expert diagnosis.
At that point, it is worth getting a professional WordPress developer to take a look.
