The question page not showing anything - Q&A Plugin

I have purchased and installed the Q&A plugin.

I created the first question, and now when I go to the question page, it does not display anything. Here is the url for the question.

http://financetrain.com/questions/what-is-the-best-way-to-prepare-for-cfa-exam/

I even tried changing the theme, but it still doesn't show anything.

Kindly help how to make this work.

Thanks,
Manish
