I have two sites on my localhost server. The other one has a problem when trying to sign in. The username and password are correct, I can access the PHP my admin and check them from there, so I know they are correct. I even changed the password from there but the new password has the same problem.
The site appears on the browser but when trying to login the error message is "The password you entered for the username is incorrect."
I have cleared cookies and cache. It doesn't help.
