This guide outlines common Apache error codes that you may encounter from time to time. If you have an issue diagnosing any of these error codes please get in touch with our support team.
400 - Bad Request - This is generally created due to a client-side error, typically when a web browser has accessed the web server incorrectly (malformed syntax, deceptive request routing)
401 - Unauthorised - This page will display usually if a webpage login is present (such as a htpasswd) and is normally served if there is a failed login attempt.
403 - Forbidden - This code will be displayed if you are trying to access a page that you cannot view, this is normally caused by permissions of a particular file or folder.
404 - Not Found - The classic http error page. You will encounter this if you are trying to access a file or folder that doesn't exist. An example of this could be a mistyped URL or a moved link.
500 - Internal Server Error - A generic message which is given when the webserver encounters any internal error.
Typically we see this error being served when either a web server is overloaded / unable to process requests. Or when a website cannot connect to a database.
