This improvement prevents customers with a blacklisted or banned IP address from checking out on your site. Normally, OpenCart allows these customers to complete the checkout process, only marking their order with the store's default order status. This means payment is successfully processed even when you don't want any orders from blacklisted/banned IP addresses.
Upload and go — utilizes vQmod so no core file modifications are necessary.
Allows customers with a blacklisted/banned IP address to proceed to the "Confirm" step of the checkout process so an order is generated in your system, but no further.
Sends an e-mail to the store administrator when an order is attempted by a customer with a blacklisted/banned IP address, with all the relevant order information.
