It is odd that the html is not in the code at all. I can see that the stylesheet and javascript are included. I noticed your theme is using visual composer plugin. I do not have a copy of VC to test against so maybe there is a conflict there.
Unfortunately, at the moment I am not sure how to troubleshoot your issue without purchasing the theme myself. But I will keep this thread open to see if anyone else has a similar issue. Then I might be able to pinpoint where the conflict is.
