I get pretty far with my custom version of magento, The version installed is the only available on the VM I´m using.
Anyway today testing totally another issue I´ve notice the place order button stop redirect to the success page.
It does instead redirect to the cart with the same product I´ve tried to check out
On the other end the order is anyway confirmed, quantity updated but no mails are either sent to confirm.
This start probably to happen after a product I requested to check out run out of quantity (I was working on another browser with the same order).
Probably a js or Php problem
Please someone come with a solution.
