cart not working after update to joomla 3.6

I updated my website to joomla 3.6 and i see that add to cart is not working. I can add a product to the cart but when i try to add another one add to cart button doesn't work and also image popup fancybox is not working.
Joomla version 3.6
vm version 3.0.16

website: giannoulakis-outdoor.gr

After a lot of research i managed to find that vitruemart fancybox causes the problem. when i disable it everything works fine. The problem is that i need it.
At chrome console i get these errors
jquery.fancybox-1.3.4.pack.js?vmver=9204:18 Uncaught TypeError: Cannot read property 'msie' of undefined(anonymous function)
Uncaught ReferenceError: sessMin is not defined(anonymous function)
Uncaught TypeError: jQuery(...).vm2front is not a function

I tried to use jquery easy but nothing happens.
Can i have any help?

Hi

For start please determine if issue is due to our template or directly in VM. Make a simple test and switch to Protostar template, let me know if it works than. If it does send me also an access to joomla panel and ftp. If this will not work still than You need to talk to VM support.

Hi

I've just found a private message asking if I have figured the problem out. I have not received an access from You, so didn't had a chance to do so. Also please read my last post and do the test I've asked for.
