Here we show you exactly what to do if the site shows a blank white page or "500 Internal Server Error" — respectively, don't panic.

Step 1: Turn on debug to see the error #

Enter cPanel → File Manager → open the folder public_html. wp-config.php. Edit. That's all, stop editing! Above in that order add these two new lines (one below the other):

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

Click Save Changes. wp-content/debug.log. wp-content → find debug.log → right button → Edit or Download.

Step 2: Turn off plugins — find the culprit #

In File Manager, go to public_html → wp-content. plugins. Rename. plugins_off. plugins_off in plugins. plugins in plugins_off. one by one subfolder from back to "plugins" (eg first move "akismet" back to plugins), refresh the site until it crashes — that plugin is the culprit.

Step 3: Check the .htaccess #

In File Manager u public_html find the file .htaccess. Rename → change name to .htaccess_old. ticket.
