Whenever i sign in forum , it says username and password is incorrect or says that your account wil unblock in 11 minutes but it does not.My password and username are correct.
Try clearing your browser's cache, and try login with the exactly same username password and write the authorization code exactly as given. And the block issue is because of repeatedly attempts of logins, as a flood system.
Notify us here if the above solutions work and next time, please provide screen shots
