When using the twitter login, after setting up the twitter app, of course, my site directs ppl to this link to login via twitter: http://my.domain.com/?&wpmudev-chat-action=pop-twitter -- doesn't popup a login page (like facebook and google+, both of which work fine on my chat) and the page is blank.
Some help would be greatly appreciated.
(I am using the latest version of chat, 2.0.6.3.)
Thanks.
