Not sure if anyone else is getting this. I'm using Chrome on a Mac FWIW.
Javascript console suggests it's a SSL cross-origin issue :-
I clicked through to the forum from a non-SSL new story page, but it's trying to load a resource via HTTPS.
Work around is to change the forum URL to
https://forums.hexus.net/ ...
I'm not sure if Hexus is officially HTTPS yet but it's nice to see security being added. Both HTTP and HTTPS seem to work though
https://www.hexus.net gives a 403 Forbidden where
https://hexus.net works fine.
