Few things cause panic quite like opening your website dashboard or typing in your URL, only to be greeted by a completely blank screen. No error message, no sidebar, no footer—just empty white space.

In the WordPress community, this is known as the White Screen of Death (WSOD).

If you are experiencing this right now, take a deep breath. You are not alone, and your website data is almost certainly still safe. The WSOD is one of the most common WordPress errors, usually triggered by a PHP memory limit exhaustion, a misbehaving plugin, a faulty theme update, or a coding error.

At ArslnMak.com, we help business owners, bloggers, and entrepreneurs troubleshoot and resolve these critical WordPress issues every day. In this comprehensive guide, we will walk you through what causes the White Screen of Death and how to fix it step-by-step, even if you are not a developer.

What is the WordPress White Screen of Death?

The White Screen of Death is an error that causes your WordPress website to display a completely blank white page instead of your normal content.

Depending on your browser (Google Chrome, Safari, Firefox, etc.), the page might look slightly different—sometimes displaying a generic browser error message like "This page isn’t working" or "HTTP Error 500"—but the underlying cause is the same.

Because the screen is completely blank, your website’s admin dashboard (yourdomain.com/wp-admin) is usually inaccessible as well. This forces you to troubleshoot the issue using alternative access methods, such as an FTP client (File Transfer Protocol) or your web hosting control panel (like cPanel or SiteGround Site Tools).

Why Does the White Screen Happen?

Before diving into the fixes, it helps to understand why this happens. WordPress is built primarily on the PHP programming language. When your site loads, PHP scripts execute in the background. If a script fails, runs out of memory, or encounters a fatal coding conflict, PHP stops executing immediately.

When PHP stops midway through generating a webpage, the server simply outputs whatever it has processed up to that point—which, at the very beginning of the page load, is nothing. Hence, you get a blank white screen.

The most common culprits include:

  • Exhausted PHP Memory: A plugin, script, or theme demands more memory than your hosting server currently allocates to WordPress.

  • Incompatible or Faulty Plugins: A recently installed or updated plugin contains a bug or conflicts with another plugin.

  • Broken Theme Files: A recent change to your theme’s functions.php file or a corrupted theme update.

  • File Permission Issues: Incorrect permissions on your server preventing WordPress core files from executing.

Step-by-Step Guide to Fixing the White Screen of Death

Let’s troubleshoot this methodically. Start with Step 1 and work your way down until your site is restored.

Note: Before making any changes to your files or database, always create a full backup of your website via your hosting control panel if you can still access it, or use your host’s automated restore points.

Step 1: Enable WordPress Debug Mode

By default, WordPress hides error messages to keep your site secure from visitors. However, when troubleshooting, you need to see what error is actually causing the blank screen.

  1. Connect to your hosting account using an FTP client (like FileZilla) or use the File Manager inside your web hosting control panel.

  2. Locate your website’s root directory (usually named public_html).

  3. Find the file named wp-config.php.

  4. Right-click the file to edit it, or download a copy to your computer and open it in a text editor (like Notepad or TextEdit).

  5. Scroll down until you find the line that says:
    /* That's all, stop editing! Happy publishing. */

  6. Just above that line, paste the following code snippet:

php
define( ‘WP_DEBUG’, true );
define( ‘WP_DEBUG_DISPLAY’, true );

  1. Save the file and upload it back to your server (if you edited it locally).

  2. Refresh your website in your browser.

Instead of a blank white screen, you may now see a specific error message pointing to a file path and line number. This tells you exactly which plugin, theme, or script is causing the crash. If you see a file name belonging to a plugin, skip directly to Step 3.

Step 2: Increase Your PHP Memory Limit

If your site ran out of memory, increasing the PHP memory limit will often instantly resolve the issue.

  1. Open your wp-config.php file again using FTP or your host’s File Manager.

  2. Find the line /* That's all, stop editing! Happy publishing. */

  3. Just above that line, add this code:

php
define( ‘WP_MEMORY_LIMIT’, ‘256M’ );

  1. Save and upload the file.

  2. Check your website.

(Note: Some web hosting providers restrict memory limits at the server level. If this step doesn’t work, you may need to contact your hosting support team and ask them to increase your PHP memory limit for your account.)

Step 3: Deactivate All Plugins

If memory wasn’t the issue, a faulty plugin is the most likely culprit. Since you cannot log into your WordPress dashboard, you will need to deactivate your plugins via FTP or File Manager.

  1. Access your website files via FTP or File Manager.

  2. Navigate to wp-content.

  3. Find the folder named plugins.

  4. Right-click the plugins folder and rename it to something like plugins_deactivated.

This action tricks WordPress into thinking that no plugins are installed, instantly deactivating all of them.

  1. Go back to your website and try to load it.

  • If your site loads: You have confirmed that a plugin caused the issue. Go back to your file manager, rename the folder back to plugins. Log into your WordPress dashboard (which should now work), go to the Plugins page, and activate your plugins one by one, refreshing your site after each activation until you find the broken plugin. Once found, delete or replace it.

  • If your site is still blank: Plugins are not the issue. Rename the folder back to plugins and proceed to the next step.

Step 4: Switch to a Default Theme

If plugins are not causing the WSOD, your active theme might be the problem—especially if you recently edited your theme’s functions.php file or performed a major theme update.

Since you cannot access the dashboard, you can switch to a default WordPress theme (like Twenty Twenty-Four) via your hosting control panel or database.

Method A: Using File Manager

  1. Navigate to public_html/wp-content/themes.

  2. Locate your currently active theme folder. Download a backup copy of it to your computer just in case.

  3. If you have a default WordPress theme installed (such as twentytwentyfour), leave it there. If you don’t, upload a fresh, zipped copy of a default WordPress theme and extract it into the themes directory.

  4. Temporarily rename your active theme’s folder (e.g., change my-custom-theme to my-custom-theme-deactivated).

  5. WordPress will automatically detect that the active theme is missing and fall back to the default theme.

  6. Check your website. If it loads, your previous theme contained a fatal error.

Method B: Using phpMyAdmin (Database)
If file renaming doesn’t trigger the fallback, you can force it in your database:

  1. Log into your hosting control panel and open phpMyAdmin.

  2. Select your WordPress database from the left sidebar.

  3. Click on the table named wp_options (note: your database prefix might not be wp_, e.g., abc_options).

  4. Look for the rows named template and stylesheet.

  5. Edit both values and change them to the name of a default theme folder (for example, twentytwentyfour).

  6. Save the changes and check your site.

Step 5: Clear Your Caching and Server Cache

Sometimes, your server or a caching plugin has cached the broken white screen version of your site.

  • Clear your browser cache and hard-refresh your browser (Ctrl + F5 on Windows or Cmd + Shift + R on Mac).

  • If you use a server-level caching solution (like Varnish, OPcache, or Cloudflare), log into your hosting account or CDN dashboard and purge the server cache.

Common Mistakes to Avoid When Fixing the WSOD

When panic sets in, it’s easy to make mistakes that complicate troubleshooting. Keep these best practices in mind:

  • Never edit production code blindly: Always make a backup copy of a file before editing it in wp-config.php or your theme’s functions.php.

  • Don’t leave WP_DEBUG enabled permanently: Once your site is fixed, remember to change define( 'WP_DEBUG', true ); back to false. Leaving debug mode on in a live production environment can expose sensitive file paths and database information to visitors.

  • Don’t panic and delete your database: The White Screen of Death rarely originates in the database. Deleting database tables will cause permanent data loss. Stick to troubleshooting files and plugins first.

Frequently Asked Questions

1. Can the White Screen of Death affect only the admin dashboard?

Yes. Sometimes your public-facing website loads perfectly fine, but when you try to log into /wp-admin, you see a white screen. This is usually caused by a plugin conflict that only affects admin scripts, or memory exhaustion specifically tied to backend processes. You can fix this using the plugin deactivation method outlined in Step 3.

2. Will my website data and SEO rankings be lost during a WSOD?

No. Your database (posts, pages, comments, settings) remains completely intact. However, if the downtime lasts for hours or days, search engine crawlers might temporarily fail to index pages. Resolving the issue quickly ensures minimal impact on your search visibility.

3. What if none of these steps work?

If you have tried disabling all plugins, switching to a default theme, increasing the PHP memory limit, and checking error logs without success, the issue may stem from a corrupted WordPress core file, a server-level PHP version incompatibility, or a severe database error.

Conclusion

Encountering the WordPress White Screen of Death can be stressful, but by following a systematic troubleshooting process—enabling debugging, raising memory limits, testing plugins, and verifying your active theme—you can pinpoint the exact cause and restore your website safely.

Maintaining regular automated backups, keeping your plugins and themes updated, and hosting your site with a reliable provider are the best ways to prevent these emergencies from happening in the first place.
