Add to Cart Button doesn't work only with a specified product

[JoeSchiaffi]

Hi there,

 

I'm using Prestashop 1.7.1 with the default theme, I've noticed a strange problem with my shop: I've some test products and all of them can be added to the cart, except one: when I click it It open the new mask that tells me "Product Succesfully added to cart" but the cart is empty! Every other product works fine, I've just noticed this. Yesterday even this product:

 

http://www.jollyrogerbay.it/shop/xbox-one/9-55-overwatch-origins-edition.html#/52-condizioni-nuovo

 

was working great and was possible to add it to the cart, now no more.

 

The only thing I've tried was to add some product options, but actually I've removed all of them, I've a similiar product:

 

http://www.jollyrogerbay.it/shop/xbox-one/10-56-overwatch-origins-edition.html#/53-condizioni-usato

 

That has same settings, and can be added to cart.

 

It's a strange problem, seems like a bug. Maybe it may be only necessary to delete that product and re-create it, but I would like to understand what the problem is because when i'll have thousands of products, it would be impossibile for me to test everyone of them by trying to add it to cart

 

Thanks in advance
