The WordPress White Screen of Death (WSOD) is a common yet frustrating issue that many WordPress users encounter. When this happens, your site displays a blank page instead of the expected content. Fortunately, there are several solutions you can try to resolve the issue. In this guide, we’ll walk you through the step-by-step process to troubleshoot and fix the white screen of death.
What is the WordPress White Screen of Death?
The white screen of death refers to a condition where your WordPress website suddenly goes blank, showing a white screen without any error messages or clues to identify the problem. It can affect either the entire site or specific pages and may be caused by several factors.
Common Causes of the White Screen of Death
- Plugin conflicts: Sometimes, one or more plugins may conflict with each other, leading to the white screen of death.
- Theme issues: A broken or poorly coded theme may also cause your site to display a blank screen.
- Memory limit exhaustion: Your site may run out of PHP memory, leading to the white screen of death.
- Corrupted core files: Faulty or missing WordPress core files can trigger this issue.
- Server issues: In some cases, your hosting server may be the culprit.
Step-by-Step Guide to Fixing the WordPress White Screen of Death
1. Clear Browser Cache
Sometimes, the white screen of death might only appear to you due to cached data in your browser. Start by clearing your browser cache and refreshing your website to see if the issue persists.
2. Deactivate All Plugins
One of the most common reasons for the white screen of death is plugin conflicts. To check if this is the case:
- Log in to your WordPress dashboard.
- Navigate to Plugins > Installed Plugins.
- Deactivate all plugins at once.
Now, visit your site to check if the white screen of death is gone. If it is, reactivate your plugins one by one to identify which one is causing the problem. Once you find the problematic plugin, consider updating it or looking for an alternative.
3. Switch to a Default Theme
If deactivating plugins doesn’t fix the white screen of death, the next step is to check your theme. Sometimes, themes may cause compatibility issues or have coding errors that lead to this issue. Here’s how to troubleshoot:
- Go to Appearance > Themes in your WordPress dashboard.
- Switch to a default WordPress theme like Twenty Twenty-One.
After switching themes, check if your site is back to normal. If the white screen of death disappears, the issue likely lies with your previous theme. Consider updating or replacing the theme.
4. Increase the PHP Memory Limit
WordPress requires sufficient memory to function properly. If your site exceeds its PHP memory limit, it may cause the white screen of death. You can increase the memory limit by following these steps:
- Access your wp-config.php file via FTP.
- Add the following line of code before the “That’s all, stop editing!” comment:
define( 'WP_MEMORY_LIMIT', '256M' );
This will increase the PHP memory limit to 256MB. Save the file and refresh your site to check if the white screen of death is resolved.
5. Enable Debug Mode
If the above methods don’t work, enable WordPress debug mode to get more information about the cause of the white screen of death. To do this:
- Open your wp-config.php file.
- Find the line that says
define( 'WP_DEBUG', false );and change it to:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );This will create a log file where you can find the errors causing the white screen of death. Check the log file in the wp-content/debug.log directory for clues.
6. Check for Server-Side Issues
Sometimes, the white screen of death may be caused by server-side issues like a temporary overload, a bad configuration, or server downtime. Contact your hosting provider to see if they can help resolve any server issues.
7. Restore a Backup
If none of the above steps work, it might be time to restore a recent backup of your website. Most hosting providers offer backup options, or you may have a backup plugin installed. Restoring a backup can revert your site to a previous state before the white screen of death occurred.
8. Reinstall WordPress Core Files
In rare cases, corrupted core files can lead to the white screen of death. To fix this, you can reinstall the core WordPress files without affecting your content or settings:
- Go to Dashboard > Updates in WordPress.
- Click Reinstall Now under the Reinstall WordPress section.
This will restore the core WordPress files, which might resolve the white screen of death issue.
Preventing Future White Screen of Death Issues
Now that you know how to fix the white screen of death, here are some steps to prevent it from happening again:
- Keep plugins and themes updated: Always ensure that your plugins and themes are updated to the latest versions to avoid compatibility issues.
- Use a quality hosting provider: A reliable hosting service can minimize server-side problems.
- Regularly back up your website: Regular backups will help you restore your site quickly if you encounter any issues.
