I found that some of the js are not loading in your server due to blocking of mixed content. So our plugin is unable to get the jquery library. Here is the details about the error. http://oi64.tinypic.com/xl9dhi.jpg .
Here the cause is that, your site is using https (SSL) and those js are being used from non https url. So it is getting blocked. Please force all urls to be ssl and this should fix the issue.
