The one problem I'm having is I cannot upload or set custom avatars. When I go to upload an avatar, I see the little loading bar thing, and when it's done, it says your avatar has been set. When I refresh the page, the avatar isn't changed. When a new user tries to set an avatar it just makes the avatar a missing image (http://woodpunchers.net/data/avatars/l/0/5.jpg?1367776472)
I know that the problem is not that the data directory is protected, because I've chmod 777'd it.
I also tried using the minecraft avatar plugin, but that won't work either.
I'd really like to not have to re-install xenforo and all my addons, so if anyone knows how I could fix this, please let me know! If you need any more info, just ask!
