Could be a caching issue

Cleared cache, still doesn't work.

It makes browsing the forum very awkward, I can't click the blue background to go to my last read message. Have to select the thread, and manually browse from the first post to the point with new messages.

And now they do show, perhaps reloading the scripts?

(although why you need a Turing complete language to read text still evades me, as always)
