WordPress White Screen of Death

The dreaded "White Screen of Death" is a completely blank page where your WordPress site should be, often with no error message at all. It looks alarming, but it is almost always recoverable. The cause is usually a PHP fatal error, exhausted memory, or a plugin or theme conflict — and each has a clear fix.

What Causes It

• A PHP fatal error — broken code in a plugin, theme, or a recent update stops the page from rendering.
• Exhausted memory — the site tried to use more RAM than allowed and was cut off.
• A plugin or theme conflict — two components clash, or one is incompatible with your PHP version.

A white screen and a 500 Internal Server Error share many of the same causes; the difference is often just whether the server surfaced the error. The recovery steps overlap heavily.

Step 1: Turn On WP_DEBUG

By default WordPress hides errors, which is why you see a blank page. Enable debugging to see what actually failed.

1. Open File Manager in cPanel and edit wp-config.php in your WordPress folder.
2. Find the line define('WP_DEBUG', false); and change it to:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

With WP_DEBUG_LOG on, errors are written to wp-content/debug.log instead of shown to visitors. Reload the site, then open that log to read the exact error.

Step 2: Raise the Memory Limit

If the error mentions Allowed memory size exhausted, give WordPress more memory. Add this to wp-config.php above the "That's all, stop editing" line:

define('WP_MEMORY_LIMIT', '256M');

You can also raise PHP's own memory_limit from the MultiPHP INI Editor in cPanel if the WordPress setting alone isn't enough.

Step 3: Deactivate All Plugins

If you can't reach the admin dashboard, deactivate every plugin at once by renaming their folder.

1. In File Manager, browse to wp-content.
2. Rename the plugins folder to plugins-off.
3. Reload your site. If it comes back, a plugin was the cause.
4. Rename the folder back to plugins. Now rename each plugin subfolder one at a time, reloading after each, until the white screen returns — that last one is the culprit.

Step 4: Switch to a Default Theme

If plugins aren't the cause, your theme may be. Force WordPress back to a default theme.

1. In File Manager, browse to wp-content/themes.
2. Rename your active theme's folder (for example mytheme to mytheme-off).
3. WordPress automatically falls back to a default theme such as Twenty Twenty-Four if it is present.
4. If the site loads with the default theme, the problem is in your theme — check its functions.php for recent edits.

Step 5: Read the Error Log

Alongside debug.log, the server keeps its own error log. In cPanel, go to Metrics > Errors and read the most recent entries. Together with WP_DEBUG output, this pinpoints the failing file and line.

Still Blank?

If you've disabled every plugin, switched themes, and raised memory but the screen is still white, open a support ticket. Include your domain and the latest lines from wp-content/debug.log and the cPanel error log so we can trace it quickly.
