Debug mode logs PHP errors so you can find what's breaking. Edit wp-config.php.
- In cPanel's File Manager, open
wp-config.phpin your WordPress root. - Find
define('WP_DEBUG', false);and change it totrue. If the line is missing, add it above/* That's all, stop editing! */. - To log errors to a file instead of showing them on screen, also add:
define('WP_DEBUG_LOG', true);anddefine('WP_DEBUG_DISPLAY', false);
Errors are then written to wp-content/debug.log, which you can read in File Manager. Turn debugging back off (false) once you're done, as displaying errors publicly is a security risk. Need help reading the log? Open a ticket and include the relevant lines.
