"The form token is invalid" error message

I am getting "The form token is invalid" error message when I try to login to a web hosting account billing panel. What could be the reason for the error message?

This error message typically means that the form token, which is used to prevent cross-site request forgery (CSRF) attacks, is not valid. This could be because the token has expired, or because it has been tampered with.

In short, when a form is submitted to a website, a token is included with the data that is sent to the server. The server then checks the token against the one that it has stored, to make sure that the form was actually submitted by the user and not by an attacker. If the tokens do not match, the server will return the "invalid token" error message.
