I have two webstores on my server:
[url removed, login to view] using Worldpay for card payments in USD, using the Pheonix Worldpay plugin
[url removed, login to view] using Secure Trading for card payments in GBP, using Secure Trading's own plugin.
Neither of the callback functions currently work - I have checked with Worldpay and Secure Trading and they both confirm that our setup with them is fine, and the problem lies with our server setup.
The Secure Trading setup on [url removed, login to view] was working until quite recently.
The Worldpay setup is a new installation but does not work.
We have recently had nginx installed on our server. Looking at the access logs it looks to me as though the server is timing out with a 302 error, which means it could be a redirect issue.
I need both of these working as we are currently getting a lot of duplicate order on our system, as customers are not sure if they have placed orders or not.
