I've nicely tuned my Xenforo site over the last few weeks in preparation for go live, and today upgraded to 1.1.3. I haven't had a single hitch up until now, but after upgrading (apparently successfully), I'm no longer able to access admin.php. The Board itself works great, without a hitch, and I can even navigate around the admin area from a window which I'd left open prior to the upgrade. It's just the admin.php which I'm unable to reach. Here's the error message: Can anyone please help? I was just about ready to go live, as well! I'd really appreciate anyone's time. Thank you.
