Hi Josh,
So the first thing here is to determine if this is a configuration issue with EDD or a problem caused by EDD Tickets.
Can you set up a regular EDD product or “download” and make a test purchase – and does the same problem occur then? If so, I’d suspect this is a set-up issue or possibly a problem with the payment gateway and you’d be better placed by seeking support from easydigitaldownloads.com.
Of course if you find the opposite – and the problem is limited to ticket products – just let me know, however EDD Tickets doesn’t actually interfere in the purchase or payment processes and this is all delegated to the actual ecommerce platform (which is, of course, Easy Digital Downloads in this particular case).
Does that help?
