Anytime I'm asked to dance and I accept, the resulting page (masquerade.php?act=invited&accept=accept) always has the JavaScript completely busted on it - I can't toggle the events part of the sidebar or press any of the buttons on the top bar.
Examining the page using Chrome's Inspect Element tool reveals that JavaScript is throwing a "Uncaught ReferenceError: __switch_obj is not defined".
EDIT: The same is true for page masquerade.php?act=invited as well.
To add to this, there are also posting issues. Anytime I go to claim a dance, I just get the "Making post now..." message and that little circle rotating forever (I left it up for thirty minutes this morning before trying to make a new post, and now the same thing is happening again). The page never changes, so I have no idea where my post is or if it's even been made without going to search (or upon receipt of a dance invite from someone else). As such, dancing is sort of not an option for users who are experiencing this issue right now.
So it isn't just me with the posting problem... I've been going to most recent two page and scrolling till I see my HA. It's kind of time consuming, but I least I can still dance.
Thanks! I did that a couple of times myself to make sure people didn't get skipped who posted above the claim posts I could locate. I saw it duplicated one of the posts too when I did that and posted twice a minute apart from one another. Looks like Keith's working on the forums now given the errors between each post though, so hopefully it'll be fixed soon. :)
