What do common errors mean (404, 500, 502, 503, timeouts)? Print

0

HTTP status codes tell you where the problem lies. As a rule: 4xx codes are client/request issues, 5xx codes are server-side.

404 Not Found — the URL or file does not exist; check spelling, case, and that the file is uploaded.
500 Internal Server Error — a script crash, often a bad .htaccess, PHP error, or wrong permissions.
502 Bad Gateway — the backend (PHP/LiteSpeed worker) returned an invalid response, often during high load.
503 Service Unavailable — the server is overloaded, restarting, or in maintenance.
Timeouts (504) — a request took too long to complete.

Check cPanel Errors for details, and open a ticket if it persists.
