How to fix a blank page on your WordPress site

What does a blank page mean?

A blank page means WordPress stopped before it could draw anything. The cause is often a PHP error. PHP is the programming language WordPress runs on. WordPress hides the error from visitors, so you see only white.

First, find out where the blank page appears:

• Only the front of the site is blank, but the dashboard works.
• Only the dashboard is blank.
• Only one page or post is blank.
• Everything is blank.

This tells you where to look. A blank front with a working dashboard often points to the theme. A blank dashboard often points to a plugin.

Fix 1: Clear the cache

1. Clear your browser cache. A cache is a saved copy of pages.
2. Clear the cache in any caching plugin on your site.
3. Reload the page.

Fix 2: Test the theme

1. If you can log in, go to Appearance and then Themes.
2. Activate a default theme, such as one named "Twenty Twenty-Four".
3. Check the site.

If you cannot log in, rename your theme's folder inside wp-content/themes using File Manager.

Fix 3: Test the plugins

1. In File Manager, open wp-content.
2. Rename the plugins folder to plugins_off.
3. Reload your site.
4. If it works, rename the folder back to plugins.
5. Turn plugins on one at a time to find the problem one.

Fix 4: Read the error

Open wp-config.php and set debug mode like this:

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

Errors are now saved in wp-content/debug.log. The last lines usually show the file that failed. Turn debug off when done.

Fix 5: Raise the memory limit

Add this line to wp-config.php:

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

This gives WordPress more working space.

Fix 6: Save the permalinks again

Go to Settings, then Permalinks, and click Save Changes. This rebuilds the page address rules.

Quick recap

• A blank page hides a PHP error.
• Note which pages are blank first.
• Test cache, theme and plugins.
• Use the debug log to read the real error.
