Hello,
We are facing an error on SNS Kalolia theme. When a product has few available units than the amount ordered by the client. I mean, for example, there are 2 items available in the store but the customer asks for 4 items and hits Buy button.
Ajax Cart shows that the product was inserted into the cart, shows its animation and its popup but none was really inserted. The cart remains empty.

Is this a known bug? How we could fix it?

I’m not sure if this is a private request, so I can send site details further, throught the appropriate means.
Thanks in advance,
Andre Gugliotti
