Duplicated orders

Hi,

Indeed, it looks like there is something really wrong.
This indicates that either:
- you must have made some kind of migration of the database, and the primary key on the order_id of the hikashop_order table has been removed, allowing orders to be created without an order_id or with the same order_id as an existing one. The "check database" button of the HikaShop configuration page will detect the problem and try to fix it if possible.
- you've changed the "order number format" setting of the HikaShop configuration page in a way which makes it non unique and potentially empty in some cases:

What did you configure in the "order number format" setting ?

Hi,

For the duplicated orders, I think it's normal. It's probably the user going back and forth between your checkout and the payment gateway for one reason or another.
That's because each time the user clicks on "finish" at the end of the checkout, the order corresponding to the cart is created.
And if the user goes back to the checkout from the payment gateway (after clicking on the cancel button of the payment gateway), the user will see the checkout again with his cart, he can potentially change things, and then click on "finish" again. So we need to create a new order as things might have changed in the meantime.

For the order without a number, I can only think that the order number has been erased, either via PHPMyAdmin, or via a mass action after it was created with the order number properly set.
