I have a site that is taking payments through WorldPay.
It takes the payment (test environment) and generated the emails.
It even gives the screen on RBS that says:
Thank you, your payment was successful Merchant's Reference: 29 RBS WorldPay Transaction ID: 114479174
However, it doesn't redirect back to the store site.
I've had my Payment Response URL set to http://greatwinesdirect.co.uk/ext/modules/payment/worldpay/junior_callback.php
I've had it set to http://<WPDISPLAY ITEM=MC_callback>
Nothing is working.
The instructions in the addon thread say:
Payment Response URL http://<WPDISPLAY ITEM=MC_callback>
Payment Response enabled? tick
Enable Recurring Payment Response tick
Enable the Shopper Response tick
Payment Response failure email address yes your email here
Attach HTTP(s) Payment Message to the failure email? tick
Payment Response password yes
MD5 secret for transactions yes
These are all done - and it's still not redirecting.
