Individual Question page is not displaying correctly

Hi,
I’m using the premium version of the DW Questions & Answers plugin with the Avada theme but the individual question page is not displaying correctly. When I click on a specific question I get re directed to a page where the header and footer disappear and only the code is displayed. On the ask question and question archive pages the header and footer works as usual. How can we solve this?
 
Thanks in advance!
