Here’s what happens when I try to get your page:
curl -v -A Twitterbot http://www.quizuple.com/quiz/prison-break

So, although it is returning a page, it also responds with HTTP 404, which I suspect causes the Cards crawler to give up. That’s a very unusual response considering you then serve up content, so I’d look at getting that sorted out.
