It is a server error code which is returned by the server what a particular webpage or the file is missing from the webhost server. Any one have another idea about it??
@frankdevineMay 24.2013 — #The 404 or Not Found error message is a HTTP standard response code indicating that the client was able to communicate with the server, but the server could not find what was requested.
The web site hosting server will typically generate a "404 Not Found" web page when a user attempts to follow a broken or dead link; hence the 404 error is one of the most recognizable errors users can find on the web.
