QnA plugin having problem displaying question after

In QnA plugin when a user submits an answer to a question he is not able to see that question page again. What user is seeing is this message

“Start/Stop notifying me of followup answers via e-mail”.

TO check this please visit below link without login

http://jbtnew.way2forum.com/questions/tretetreter/

again visit the same link after login with below credential

You will see the difference.

Why user is not able to see question page and answers??

Thanks
