I can’t see comments anymore—what was recently changed?

I can’t see the comments under posts anymore. This just started happening in the last day or so. (If I know a comment is there, I can still see it in the “recent comments” section.) I’m using IE8 at work (CORRECTION: IE7), where a lot of stuff is blocked for security reasons, but not in a way that kept me from seeing comments until recently.

What changes were recently made to the site that would cause this? It would be really nice to undo those.

Btw, I won’t be able to see the replies to this post unless I find them under “recent comments”, so … if you want more specifics about how it looks on my end, you’ll probably have to PM me.
