Problems with comment systems

Hello. I have problem with my two websites, where I installed Catch Responsive. My problem is that any comment systems doesnt work, for example plugin Disqus... on one site plugin with commnet system has been installed earlier, but it was on a different template, and when I installed your template on the new pages that I add comment system is not working. At the other site that I created directly on your template commenting system is also not appear.
