After a failed attempt to fix the cross-posting glitch that appeared after updating the forum I decided to reinstall it and update it at the same time.
Bad idea.
I’ve now installed, broken and uninstalled the forum five times in a row just to get it to work again. Sorry if your avatars or any other file you’ve uploaded disappeared but that was because of a very freaky PHP/FTP error that made me have to completely empty the folder (which didn’t even work at first)
Anyway, enough about that. The forum’s fixed now, report any bugs if you find them (like not being able to see the forum, that bug is very sneaky)
