products no longer available in the cart

[aelle robbiani]

Hi all,

I have a problem with the products no longer available in the cart.

If a guest user does a cart and leaves it, returning a few days later he found it. If a product in the meantime is no longer available I see correctly "not available", but prestashop concluding the order bringing the product in question to -1.

The product in question has the setting to refuse orders when out of stock.

I would like to know at first if you ever happened something like that, and at second if it was possible to not seeing the carts abandoned at guest users like to registered customers (Preferences-> customers-> no on show cart on login).

Thanks to everyone
