Mitchell TrevorIf you’ve been using WordPress for a while, you might have encountered the infamous “White Screen of Death” (WSOD) at some point. This issue can be quite frustrating, as it typically leaves your website looking completely blank, making it impossible for visitors to see anything. In many cases, this error is caused by problems related to WordPress plugins. Fortunately, there are several ways to troubleshoot and fix the white screen error, and in this article, we’ll explore 5 WordPress plugin tutorial white screen error solutions that can help you get your site back up and running in no time.
What is the WordPress White Screen of Death (WSOD)?
The White Screen of Death (WSOD) in WordPress is a common error that leaves your site completely blank, with no error message, content, or anything visible. This can happen when there’s an issue with a plugin, theme, or a conflict between the two. Most often, it occurs after updating or installing a new plugin, making it difficult to pinpoint the exact cause.
Some common causes include:
- A faulty plugin update or installation
- A conflict between plugins
- Insufficient PHP memory
- A theme incompatibility
- Corrupted core files
While the error itself might look alarming, there are simple steps to fix it, especially when the issue is related to plugins.
How to Diagnose the WordPress White Screen Error
Before jumping into the solutions, it’s important to diagnose what’s causing the white screen error. Here’s how you can do it:
- Enable WordPress Debugging: By enabling the debug mode in WordPress, you can get more detailed error messages that can help pinpoint the issue. To do this, add the following line to your
wp-config.phpfile:define( 'WP_DEBUG', true );This will display any PHP errors or notices on your site. - Check the Error Log: Most hosting providers offer error logs. If you can access the logs, check for any specific errors related to plugins, themes, or memory limits.
- Use a Plugin: There are plugins that help with debugging, such as the “Query Monitor” plugin, which can provide deeper insights into your site’s error log.
Once you’ve diagnosed the issue, you can start working on fixing it.
Solution 1: Deactivate All Plugins
One of the first steps to resolving the WordPress white screen error is to deactivate all your plugins. It’s possible that one of the plugins has malfunctioned or is incompatible with your WordPress setup, causing the issue.
Here’s how to deactivate all plugins:
- Access Your WordPress Dashboard: Log in to your WordPress admin panel.
- Go to the Plugins Page: Navigate to Plugins > Installed Plugins.
- Bulk Deactivate Plugins: Select all plugins and choose the “Deactivate” option from the bulk actions dropdown. Then click “Apply.”
If the white screen disappears after deactivating the plugins, you know the issue is related to one of the plugins.
To identify the faulty plugin, reactivate your plugins one by one and check your site after each activation. When the white screen appears again, you’ll know which plugin is causing the problem.
Solution 2: Check for Plugin Conflicts
Sometimes, two or more plugins might conflict with each other, leading to the white screen error. To check for plugin conflicts, you can:
- Deactivate All Plugins: Follow the steps mentioned above to deactivate all plugins.
- Activate Plugins One by One: After deactivating all plugins, reactivate them one by one, checking your site after each activation to see if the white screen appears again.
- Test for Conflicts: If the white screen appears after activating a specific plugin, there’s a conflict between that plugin and another plugin on your site.
To resolve the conflict, you can either contact the plugin developers for support or find an alternative plugin that performs the same function.

Solution 3: Increase PHP Memory Limit
Another common cause of the white screen error is insufficient PHP memory. WordPress requires a certain amount of memory to run, and when this limit is exceeded, it can lead to the white screen issue. Here’s how to increase the PHP memory limit:
- Access the
wp-config.phpfile: This file is located in the root directory of your WordPress installation. - Edit the File: Add the following line before the “That’s all, stop editing!” line:
define('WP_MEMORY_LIMIT', '256M'); - Save Changes: After saving the file, refresh your website to check if the issue is resolved.
If you’re unsure how to edit your wp-config.php file, you can find more information in our WordPress troubleshooting guide.
Solution 4: Switch to Default WordPress Theme
Sometimes, your active theme might be the cause of the white screen error. A theme incompatibility or a coding issue in the theme files can trigger this problem. To test if the theme is the issue, switch to a default WordPress theme, like Twenty Twenty-One or Twenty Twenty-Two:
- Go to the WordPress Dashboard: Navigate to Appearance > Themes.
- Activate a Default Theme: Select a default WordPress theme and click “Activate.”
- Check Your Site: Refresh your site to see if the white screen error is gone.
If the white screen disappears, it’s likely that your previous theme was the issue. Consider updating or replacing the theme with a more compatible one.
Solution 5: Reinstall the WordPress Core Files
In some cases, the white screen error can be caused by corrupted WordPress core files. To fix this, you can reinstall the core WordPress files:
- Backup Your Website: Before making any changes, it’s important to back up your site.
- Reinstall WordPress: Go to Dashboard > Updates and click on the “Reinstall Now” button. This will reinstall WordPress without affecting your content or plugins.
