Can't login even after resetting password

After I login (attempt)... I do not get an error message.
The URL shows this at the end : "&defender_login_message=session_expired"

I've tried resetting the password.
Logging in with it shows the same message in the URL but nothing on the screen.

If I try an invalid login, I do get an error message.
So that part is working.

And pointers to get me in into the Dashboard?

Thanks,
Roland
