cPanel keeps a log of recent server errors for your site:
- Log in to cPanel.
- Under Metrics, open Errors. This shows the most recent web server errors (404s, 500s, permission issues, and more).
For application-specific errors, also check:
- PHP error log - often a file named
error_loginsidepublic_htmlor the affected folder (view it in File Manager). - CMS logs - for example WordPress debug logs in
wp-content/debug.logwhen debugging is enabled.
The cPanel Errors page only keeps the latest entries, so check it soon after a problem occurs. If you cannot tell what is causing repeated 500 errors, copy the relevant log lines and open a ticket so support can help.
