When one clicks on the button add to cart it just works. It goes straight to the checkout page as it should. But when they want to order that product again for some reason in the same tab (maybe they go back and want to know a little bit more information about the product) it goes straight to the homepage and it does not work. It does not say any error like: you cannot order this product twice or whatever … It just goes to the homepage including the /?add-to-cart=xx behind the url.
Can you fix this? Because I have a product (a free book + shipping offer) and I do not want people to order this product twice in 1 order.
If you go to this URL: https://puppygroep.nl/gratis-boek and press the green button. You then will land on the checkout page. If you go back to https://puppygroep.nl/gratis-boek and press the green button again. You’ll see that you will be redirect to the homepage with this url: https://www.puppygroep.nl/?add-to-cart=13222.
