Twitter login doesn't appear to be working in the new version

I like the added functionality of the new chat. However it doesn't appear that users can login with Twitter. I sign in and go through the whole authenticating process with Twitter but when it's done it says "You must login to participate in chat". Previously with the old version it worked on my site.

Here's the URL so you can test it to see if it's just me.

Logging in with Facebook worked just fine.
