I have some problem setting up my PayPal payments with opencart. I am new to opencart so I think I have done something wrong. First of all, my website only contains downloadable goods.
When someone orders a product and they pay with PayPal they return to my website and the order wont show up on their account.
When I log in as admin and I dont see any orders. I only see that the order was made in my Recent Activity Tab on the dashboard.

When I click on that order I see that the Order status is Canceled and I need to set it to complete or else the customer doesnt get a email that the order has been completed.

I have set up my PayPal to these settings. Have I done something wrong? I want that the customers automaticly get the status complete and that they immediatly download there product(s).

Hope you guys know what I mean.
Kind Regards,
Wesley
