Problems accessing forums?

[Chillout80s]

Since recent updates to the site here, I seem to have issues viewing threads. I can go into a particular forum and view the topics but when I click on a topic and try to view it I just get the following. (see attachment).

Doesn't happen on any other forum I visit, and I've tried multiple different browsers, clearing cache, etc.

Anybody else having this issue?

Thanks, love the site!!
