My nexus store has been operating for over a year now and ten days ago my forum started this issue.
When you try to order, the order process goes smooth all the way until you go through and complete payment with paypal. Then I get this page that says the order has already been completed. The order never processes with paypal though.
Any idea why I would be getting this??? Paypal issue or IPB Nexus issue.
Below is the page that shows after every order is placed through paypal.
