what does 404 error means
The 404 or Not Found error message is an HTTP standard response code indicating that the client was able to communicate with a given server, but the server could not find what was requested.hile many websites send additional information in a 404 error messageâsuch as a link to the homepage of a website or a search box âsome also endeavor to find the correct web page the user wanted. Extensions are available for some popular content management systems (CMSs) to do this.
