Hello,
I have a little problem. A User can't logout. He went from his Computer in the evening and he has forgotten to logout. Today he go back to the computer and everytime when he click at the button logout he come back to the first site and he is activate. Please help me.

And excues me my not so good english. I'm a german and my English is not so good and the German forum is closed for the moment.

The problem is away.

After a complete deactivation of the forum can everybody login and logout.
(login was inpossible, too)

User CP --> Edit Options. Uncheck the setting "Remember my login details..."

Thank you
