Shouldn't matter if Remember Me is set or not. Remember Me just saves your username so it's easier to log in. The problem is it logged me out for no reason. Usually auto logouts are triggered by x minutes of inactivity but in this case I was working on the post so the inactivity timer should not have timed out.
In addition I never got a warning "we're about to log you out, click to stay logged in" after x- minutes of inactivity as most sites do?
I'm on a macBook, does that matter? Am I doing something wrong?
