A 404 Page Error or Not Found error is displayed when you go to a page that doesn't exist within an active website.

A 404 error is an HTTP status code that means that the page you were trying to reach on a website couldn't be found on their server. The 404 Not Found error might appear for several reasons even though no real issue exists, so sometimes a simple refresh will often load the page you were looking for. The most common method is to retry the web page by pressing F5, clicking the refresh/reload button, or trying the URL from the address bar again.

A 404 error is returned by a web server (the machine where a website is hosted) when it cannot find the page you have requested. The most likely cause of this error is a mistyped URL.
