Fix common WordPress errors

White screen or 500 error

Almost always a plugin or theme.

1. In the file manager rename wp-content/plugins to plugins-off — the site should load.
2. Rename it back and re-enable plugins one at a time to find the culprit.
3. Turn on define('WP_DEBUG', true); in wp-config.php temporarily to see the error, then turn it off.

"Error establishing a database connection"

Check the database name, user and password in wp-config.php match your hosting database, and that the database exists. Restore the correct values or ask us.

"Allowed memory size exhausted"

Add define('WP_MEMORY_LIMIT', '256M'); to wp-config.php, and deactivate heavy plugins.

Stuck in maintenance mode

Delete the .maintenance file in the site's root folder.

Redirect loop

Set both WordPress Address and Site Address to the same https:// URL and clear your browser cache and site cache.

Hacked or redirecting to spam

Restore a clean backup, change all passwords, update everything and delete unknown admin users and plugins.
