I have a custom Prestashop payment module that works fine most of the time. Sometimes though the payment is successfully taken but no order is created in Prestashop, therefore I can't always tell if an order has been placed.
As the error only happens some times it is hard to trace why it is happening.
I need someone who is familiar with Prestashop payment modules and gateways and can resolve this.
This is the developer guide for the payment gateway [login to view URL]
I'll provide the other details on acceptance.
