@Eddy:
About the site update, it was mainly about content and member-related updates that I'm not privy to since I'm not a member, so I knew that wasn't it.
@Pondus:
Yeah! That was what I was dealing with, too! I just checked the site a few minutes ago and I was able to visit normally. I think the guy who runs the site found the problem, phew!
To all: Thanks! The site is working normally again! The guy who runs the site was able to circumvent that problem!
Edit: I just tweeted the site owner and he said it was his cache!
