Hi,

You have that error on the product page when you click on the add to cart button:
monosnap.com/file/pd2UfVc8Q2fCR8rETiAAHeiiKXuzaQ
The issue apparently comes from the extra parameters being sent:
monosnap.com/file/BFcqg5wdc4o0LDUsCLYzxwAGe8lp85
These come from the contact form that you included in the product page.
While that's not a problem per se, you should move that form outside the form tags of the product page. Then, they wouldn't mess with the standard add to cart process.

Hi nicolas thanks for your great and fast support.
I decided to remove contact form from product page, it's not so crucial. Everything works fine.
