Hi. The extension SNS Proaddto is not working on my theme SNS Simen . When I click in the addtocart button I get an error that the product couldn’t be added to cart. It only happens in product page. If I click on category page it’s added fine.

The url is http://www.lederflohmarkt.de . Actually it´s closed for developing. I need your ip to open an access for you.

Thanks.
