First, it kept logging me off of Facebook, which I've never heard of.
While I was logged out of Facebook, it kept refreshing my forum homepage on its own - again, never seen this.
If I click the admin link up top, it takes me back to the login screen, although it acknowledges I'm already logged into my account, and it point blank refuses to accept my password.
And now I'm unable to log out of my account. Whichever way I try it, it just redirects to my forum front page.
Completely baffled at all of this. Does anyone have any ideas please? I've tried different themes, and the standard default them, with the same result. If for some reason I'm booted out of this one admin window I have open, that'll be it - I won't be able to get back in.
