Thank you page not showing

[sergej_k]

Hi,

I'm testing a payment processor I've developed (actually an Omnipay gateway for the Omnipay Multiprocessor but that's not relevant, I believe). The redirection to the gateway site is working and after finishing the payment I'm redirected to this URL: http://localhost/civicrm/civicrm/contribute/transact?_qf_ThankYou_display=1&qfKey=a8e39a500446948e4e6d244a7b641eed_8275&lotsOfOtherParamsFromTheGateway

So apparently a Thank You page should appear but instead I see the confirmation page that I was originally redirected from (the one with the Continue>> and Back buttons). This is probably some misconfiguration but I have no idea what it is. Can you help? What should I check?

I'm using the Bitnami CiviCRM stack.

Thanks!
