Something wrong with the site?

My front page says: 0 new messages -4 unread messages. I have no new messages, nor any unread messages either?! Every time I post I get a hang up that seems to last a minute or when I check out a thread I haven't been to, otherwise ok. It's only doing this on this particular website not others so I'm not sure what's up.

 

performance has been a bit slow this morning.

 

Yeah, it's the only site that's crawling for me as well.
