Error when login by press key enter

Please help me
Can you tell me which Authentication type do you use - Forms (old) or Claims-based (the new one)?
You can check this by going to Administration > Settings > User Authentication
Depending on the authentication type you need to use one of the two Login widgets available in the Page's toolbox: one of the them is for Forms authentication - it says for backwards compatibility.
Maybe you're using the wrong Login widget?
