On my end, trying to view any profile or modify your settings logs me out, but other than that you can still see your favs, add new favs, upload stuff, and I'm about to test if posting on the forum still works lol.
Edit: You can still use the forum :v Edit 2: You can actually modify your account settings, but not look at your profile while logged in.
There are several errors and they have all been reported to slayer duck. for now just don't click on any username or the 'My Account' button as those seem to be the most broken.
