If you’re experiencing this error from the error log – “N:-5003: The order already exists in the database. The order has the same Order ID, so it will not be processed – merchant must generate new payment URL with a new invoice id, and this should allow the transaction to go through.”, this is due to the fact that most of the payment systems require every orders ID to have a unique value, this includes Tyl By Natwest’s payment system. This error message means that you cannot pass over a multiple instances of orders with the same IDs.
As a workaround, you can use a third-party plugin called Custom Order Numbers for WooCommerce, this plugin can let you change the order ID to a much higher order ID which should be able to resolve the issue as the numbers will be assigned to new orders automatically. Please take note that this is a third-party plugin and you will need to contact Tyche Softwares‘s support if you need assistance or clarification with their plugin’s functionalities.
