Hey DJ. Interesting issue; thanks for pointing it out. I’m unable to recreate this on my default 2011 install with no other plugins active…which makes me think there may be a conflict here. Any chance you’re in a position where you can test deactivation of other plugins (and reverting to the 2011 theme, as needed) so we can see if there is a conflict there?
One solution that may work – and is worth a shot – is to just resave your permalinks and give it another go. Sometimes weirdness arises upon installation that can be fixed with a resave of that permalinks page. Let me know either way and I can get a dev to try and help you out from there as needed.
