I'm getting the above error when I go to check my test question. I'm using Wordpress 3.3.

Also when I try to answer the question I get a page which comes up that the Answer must be associated to a Question. I assuming that since I'm answering it on the question page it should automatically be associated with that question.

And one last question, if I have more than one question, should the questions be listing down the page or in page tab numbers. I have two test question and instead of listing down the page like in the screen shot, it shows one question and then I have to click tab for the second question.
