I posted this question a while ago under a different user - I can't comment on that one, so I'm reposting. Hope that's OK!
I'm having a problem with exp-resso whereby my client is receiving payment for orders made on the site but the orders are not appearing in the 'Orders' section of the store - they are remaining as 'Incomplete'
The first port of call would be the payment gateway, as it appears not to be flagging payment. However, the problem is appearing with both PayPal Express AND the Barclaycard EPDQ gateways.
Any pointers?
EDIT Apparently users are getting redirected to the order confirmation page as expected, but there is no order confirmation ail generated, and the order remains at 'incomplete'
Using EE 2.53 and Store 1.6.4
