Weird Problem: even if customers can't even view disabled products, they keep purchasing them

[JoeSchiaffi]

Hi there,

Using Presta 1.7.2.0 default theme

I've installed a module that automatically disable products when quantity is 0 and set the shop in order to not allow customers tu order out of stock products. If products are at quantity 0, they got disabled so it's even impossible to view them, but here comes the strange parts: since 7 december, I've started to receive orders containing disabled and zero quantity products, these orders are with the status "Reservation of a product. RElease confirmed" and the customer receive the Out of stock notifications, these products are (after the order) with quantity inferior to 0, so -1.

I can't figure out the problem, just now a customer ordered to me a product that was disabled and was not viewable on the site: how does he view it? And even if, it is totally impossible to put it into the cart, so what's happening here?

 

I was Using FMN preorder and notification products since 2 weeks ago, but disabled it because is the  worst module ever used: full of bug and they didn't even tested on Internet Explorer so with IE wasn't possible to add products to the carts, but I've disabled (and just now uninstalled) that horrible module, so it shouldn't give any more problem, it's the only module related to quantity and out of stock products. The other one module (the one that automatically disable product when quantity is equal to 0) works fine. The first order with disabled product arrived on 7 december and I didn't to nothing in that date, so I'm really confused here guys

Find out the problem, it's a BIG PRestashop Bug: if a customer put a product into the cart, then leave the side, then come back after some days (and in the meanwhile the product has been disabled because no longer avaiable) the product still remains into the customer cart and if it complete the order, he can purchase it even if it's 0 quantity so it became -1 quantity!

How can such a big problem pass unseen by prestashop developers?

there are lot of open topic with this incredible bug:
