WordPress Certified Editor Exam 2025 – 400 Free Practice Questions to Pass the Exam

A 404 error indicates that a user is trying to access a web page that is not available on the server. This typically happens when the page has been deleted, moved, or the URL was entered incorrectly. It's a specific HTTP status code that signals that the requested resource could not be found. This error is commonly encountered on the internet and serves as an indication to both users and website administrators that the link or URL they are trying to access is no longer valid.

The other options describe different scenarios that do not correspond to a 404 error. For example, incorrect login credentials would result in a different error code, while maintenance would likely trigger a message indicating that the site is temporarily down. Similarly, a server overload might produce a different status code, such as a 503 service unavailable error. Therefore, the correct association of a 404 error solely relates to the unavailability of a specific web page requested by the user.
