I'm working on a Craft Commerce 1.2.1331 site using Worldpay but I'm having problems with Worldpay test transactions not completing the order first-time.
Users are redirected from Worldpay to the Order Thank You template but the order is not being marked as Complete. It remains an active cart. Then, if you checkout again, the order is marked as complete and the cart is emptied. Anyone?
There's nothing in the logs. Actually, there isn't a Commerce log.
