This issue seems to have fixed itself after I added the "ssl off;" directive
(without quotes) to the above server block. After I restarted nginx, I
cleared out and reinstalled the affected forum software, and the issue
hasn't reappeared yet, not even after clearing my browser cache, rebooting
the computer, then revisiting the forums.

I though "ssl off;" was supposed to be the default if the ssl setting isn't
specified?
