It isn’t working for me either. Just FYI. I tried removing my bit.ly API key, and my Facebook OpenGraph ID, and it still doesn’t put a link in the tweet popup. It’s got my Twitter username, and the title though.
Dude, I managed to fix it.

It must have been a plugin update that stuffed things up.
I am having the same problem.
The login URL changes, but nothing is displayed on the page. No Dashboard, no login options.
