Hello,
We are experiencing issues with out payment response page, we are using magento 1.9 and a realex plugin from studioforty9 to process our payments, all seems to work great up until I activate the ssl, without it the payment process goes fine, the realex payment page shows, we fill it in and we then get redirected back to our your order completed successfully page, however with the ssl activated we get “Your transaction has been successful but there was a problem connecting back to the merchant's web site. Please contact the merchant and advise them that you received this error message.”
