Problems and site template virtuemart 2

[rostrato]

Hello to all the forum.
It is my first experience with Virtuemart 2 and having it installed on site with free template JSN Decor, noted that there are no items in your cart after clicking "add to cart".
Can I kindly get info to fix this solution?
Thanks to all
