Paypal Payments Advanced confirmation message not appearing
I'm in the final stages of launching a Magento 126.96.36.199 site and the only hurdle left is the Paypal Advanced Payments set-up, which has been a bit more trouble than we anticipated. We're keeping the payment window hosted on our site (Option C), but upon submitting the credit card information, no confirmation page/message appears. The payment window just disappears and the space below the shopping cart information just stays blank. Payment is however processed and the confirmation email is sent out.
According to Paypal everything has been set up correctly on the Paypal Manager side, and they think there's something wrong with the template or with a Dashboard setting. Paypal has suggested that Magento is passing a return URL which is overriding the return URL settings in our Paypal Manager account. I'm 99% sure there's no dashboard setting for this, and I'm struggling to find this and what to do once I do find it. Any suggestions?
