Thanks for the links!
The issue right now is not the shortcode but the fact that there're two versions of the jQuery script loading: one is at the top ( jQuery v1.11.3) and the other one (jQuery v1.11.0) is included after the footer. Joomla recommends using the first one which comes with Joomla and plugins and templates are expected to check first to see if the native jQuery has been already included...
So that last jQuery script that likely comes with your template overrides previous jQuery namespace where our plugin is referenced so it basically can't be found when the page is loaded.
You would need to remove the duplicate loading of jQuery in the footer of the page to make it work. It will help with other unexpected issues in the future!
Let us know if you need help with this.
PS: you would need to remove these two lines at the bottom of the pages:
