Doesnt put products to /cart

[tygo]

Hello,

I have the problem, that on product pages like http://www.glasfoto.com/raffael-engel-schluesselanhaenger-mit-led-30-x-20-x-15-detail.html the products aren´t put into the basket (/cart) when I click on the green button.  The problem exists in Internet Explorer 11 (Chrome and Firefox works). I gues that there is a conflict between jquery libaries or something like that but can´t handle it.

Thank you so much for any advice!
