[Plugin: Jigoshop – WordPress eCommerce] Variable product and the add to cart bu

Hi,

I created a variable product. All the choice are showing on the shop, I can choose the type I want, no problem.

The problem is when I am on the shop first page with all the products, I can add the product directly from this point in the cart, with the add to cart button. It is working well for the simple products, but for the variable one, when I click on the button, I have a blank page and I need to reload the page to have the warning “Please choose product options…”

Does someone have an idea ? thank you
