The main site is still hosted on our old server with Lunar Pages, and, unfortunately, they've got some sort of PHP errors going on. This is causing our site (and likely others on the server) to display HTTP 500 Internal Server Errors.
As this is just a basic shared hosting package, I, unfortunately, can't do anything about it at this time. We'll have to wait until they resolve the issue.
I've asked Madog to submit a ticket to Lunar Pages to hopefully expedite the situation as I'm not on the paperwork, but hopefully they'll get it resolved ASAP.
Just another reason I'm anxious to get the new site ready to go so that we can leave Lunar Pages forever.
