Currently running a fresh new 4.4.10 install from the release from this site and I'm experiencing some very weird behaviour. I'm able to login as a member, however, when I try to login into the ACP, the page does nothing but just refresh.
Ocassionally, I can "login" by spamming the login button and end up on the admin dashboard with an error message about csrf key mismatch (still doesn't really solve the problem)... which could be a clue, but I'm currently not sure where it'd lead to as I'm not very familiar with the code of this forum software. Another thing I noticed is that sometimes the querystring will have "error=NO_ADSESS" in the URL bar, so my guess is something with sessions.
But I digress... so far, I've tried everything I could think of: I've tried multiple versions and different releases from different vendors, reinstalling nginx, trying out nginx configs specially for IPS, but nothing...
Tried versions worked before on a machine I've had before, so I'm not sure what the deal is.
For what it's worth, I'm currently runnig PHP 7.2 and Nginx 1.17.
