Question & Answer Plugin

I can't seem to set up Q&A as a category on my site. Also, when creating a Question for testing and trying to preview it, or even view it after publishing, I keep getting the message, "Cheatin uh?" And the one time I was in fact able to view a question live on the site, it displayed nothing for me. Please help. The domain is coptichymnsclass.com

Thanks,

George
