The forum is currently down.
The Host and admins have been notified.
Edit: Staff has been informed and the database is being worked on and the PHP version is being upgraded.
May 21 update:
Okay, turns out the site was causing an abnormal load on the server, and my hosting company disabled the database. It's been re-enabled and we should be able to update the PHPBB installation now.
I didn't get the notification they supposedly sent me about it.
