Hello guys, I've found what I belive is an error:

In my shop I can add the product to the cart from the product info page or from the product listing directly.

When you add it to the cart zen cart take you to the cart page where you can find the button "continue shopping"

If you reach that page from the product info page and you click on the Wcontinue shopping" it takes you back to the product page, but if you do the same addig the product from the listing it say "product not found"

Someone can help me?

Alessandro
