Internal Server Error?

My website, http://getchan.net/ is experiencing some sort of server problems. Now, let me just say that I have no idea how any of this stuff works. My co-administrator recently quit on me, and he was the one who dealt with this type of thing. For now, though, I just want to get the site back up. It may be difficult since I’m new at this, but any help would be appreciated.
