Frequently Asked Questions

HTTP 404 means 'Not Found' — the server cannot find the requested resource. This usually means the URL is wrong, the page has been deleted, or there is a typo in the link.

401 Unauthorized means you need to log in (authentication required). 403 Forbidden means you are logged in but do not have permission to access the resource (authorisation failure).
