Hi – I’m sorry you are experiencing difficulties.
WordPress and indeed our plugin both use a library called jQuery. It’s important that jQuery is added only once and is a currently supported version (ie, it is the same version that ships with a supported WordPress release).
On your site that library is present, but jQuery has been added a second time by your theme:
themes/scn03/jquery.js
This is creating a conflict as we have two different copies of jQuery present (and they are two different versions). Can you look into resolving this in the first instance, perhaps by talking to the theme author?
