The WordPress White Screen of Death: What is it and how to fix it?

While this article is a guide fixing the WordPress White Screen of Death, if you need assistance in converting your WordPress site into a mobile app without coding, get started here.

Few errors strike fear into WordPress users like the White Screen of Death (WSOD) — a blank white page where your website used to be. No warning, no error message, and no clue what went wrong.

If you’ve ever opened your WordPress site only to see a white void, don’t panic. The issue is fixable — and usually reversible with the right steps. In this 2025 guide, we’ll explain what causes WSOD, how to fix it, and how to prevent it from happening again.

What is the WordPress White Screen of Death?

The White Screen of Death occurs when your WordPress website can’t load properly, leaving users with nothing but a white, empty page. It’s one of the most frustrating WordPress errors because it offers no error message or diagnostic hint.

For most site owners, the WSOD results in website downtime, loss of visitors, and a potential hit to revenue or SEO rankings. And if your WordPress website is connected to a mobile app (for example, built using AppMySite), that downtime affects your app’s performance too — since the app relies on your website to fetch data.

Understanding the causes behind this issue is the first step to recovery.

Common causes of the WSOD error

While WSOD looks simple on the surface, the root cause can vary widely. Some of the most common triggers include:

  1. PHP memory exhaustion
    When your website exceeds its allocated memory limit, WordPress can’t load all its resources, resulting in a white screen.
  2. Faulty plugins or themes
    A poorly coded or incompatible plugin/theme can break your site’s structure or overload your resources.
  3. Server-related issues
    If your hosting provider experiences downtime or your server has resource constraints, it can lead to temporary WSOD errors.
  4. Corrupt files or scripts
    Broken code, file corruption, or conflicts in your theme’s functions.php file can cause WSOD.
  5. Caching conflicts
    Cached files can sometimes conflict with your latest site updates, creating display or load issues.

Now that we understand why it happens, let’s go step by step through how to fix it.

How to fix the WordPress White Screen of Death

Before troubleshooting, always back up your website. Most hosting providers offer automatic backups, but it’s good practice to create a manual backup as well.

Once that’s done, try the following fixes in order:

1. Clear your browser and website cache

Sometimes, the WSOD appears because of outdated cached data.

Steps:

  • Clear your browser cache and cookies.
  • If you use a caching plugin (like WP Rocket or W3 Total Cache), log in to your WordPress dashboard and purge the entire site cache.
  • If you can’t access your dashboard, clear your cache manually through your hosting control panel.

Reload your site afterward. If it loads normally, the issue was caching-related — a quick and easy fix.

2. Increase your PHP memory limit

If your site still shows a blank screen, a PHP memory limit issue may be the culprit.

Fix:

  1. Connect to your site via FTP or your hosting file manager.
  2. Locate the file named wp-config.php.
  3. Add this line of code just before the line that says “That’s all, stop editing! Happy blogging.” define('WP_MEMORY_LIMIT', '256M');
  4. Save and re-upload the file, then refresh your website.

If the site loads successfully, your WSOD was caused by low memory. If not, remove the added line and move to the next solution.

3. Deactivate all plugins

Faulty or conflicting plugins are among the most common reasons behind WSOD.

Fix via FTP:

  1. Log into your site using FileZilla or another FTP client.
  2. Navigate to /wp-content/ and locate the plugins folder.
  3. Rename the folder to plugins.old — this will deactivate all plugins.
  4. Reload your website.

If the site loads, you’ve found the issue. Rename the folder back to plugins, then deactivate plugins one by one by renaming their folders individually.
Once the site breaks again, you’ll know which plugin caused the problem. Delete or replace it with a safer alternative.

Tip: Always check plugin reviews and update histories before installing new ones. Outdated or poorly maintained plugins are often the root of critical site errors.

4. Switch to a default WordPress theme

If disabling plugins doesn’t help, the issue might be theme-related.

Fix:

  1. Access your site files via FTP.
  2. Navigate to /wp-content/themes/.
  3. Download your current theme folder (for backup).
  4. Delete it from the server. WordPress will automatically revert to a default theme like Twenty Twenty-Four.
  5. Refresh your website.

If it works, the issue was caused by your theme. In that case, review your theme’s functions.php file for errors, extra spaces, or missing PHP tags. You can also reinstall a fresh version of the theme.

5. Enable debugging mode

If none of the above steps work, WordPress’s debug mode can reveal the source of the issue.

Steps:

  1. Open your wp-config.php file again.
  2. Add the following lines: define('WP_DEBUG', true); define('WP_DEBUG_LOG', true);
  3. Save and upload the file.

Reload your website. You may now see a specific error message on the screen, or a debug.log file will be generated in your /wp-content/ folder.

This log file will indicate which plugin, theme, or script caused the WSOD. You can share this with your hosting provider or developer for deeper investigation.

When to contact your hosting provider

If you’ve tried all the fixes and the white screen persists, your hosting provider might be the root cause. Server outages, misconfigurations, or permission issues can sometimes trigger WSOD.

Contact your hosting support team and share the debug log or details of your troubleshooting steps — managed WordPress hosts typically resolve such issues quickly.

How to prevent the WSOD in the future

Prevention is always better than recovery. Here’s how to minimize the risk of encountering the WSOD again:

  • Keep WordPress, plugins, and themes updated.
  • Regularly monitor your site’s performance using uptime tools.
  • Avoid installing unverified plugins or themes.
  • Use managed hosting with WordPress-specific optimization.
  • Maintain regular off-site backups for safety.

If your WordPress site powers an app (through AppMySite), keeping your site error-free ensures your app remains stable, updated, and fully functional.

Final thoughts

The White Screen of Death might look intimidating, but it’s rarely a permanent issue. By systematically clearing cache, checking plugins and themes, and using debug tools, you can usually restore your site in minutes.

A reliable hosting provider and good maintenance practices can prevent it from recurring. And if your website powers a mobile app, resolving WSOD quickly ensures uninterrupted app performance too.

If you’re ready to make your WordPress website more accessible, secure, and mobile-friendly, try building your own app with AppMySite — the fastest way to go from website to app without coding.
