I have configured PayFlow Link on Magento 1.6 which is my live project used live payflow link account and configured everything perfectly as required with all details. Also enabled debug mode to see the request and response which are correct but the issue is whenever i finally submit order for pay on payflow by clicking on “Pay Now”, Payflow link show me a error mentioned below.
Some required information is missing or incorrect. Please correct the fields below and try again. Error: Invalid Merchant or Merchant doesn’t exist!
Whereas i tried on Magento 1.8 and 1.9 it worked very well.
Any body have faced this issue? If yes, how to solve it.
Also i found that the payflow.paypal.com is being called twice once when i click on pay now and secondly automatically navigate to payflow.paypal.com
P.S. I dont want to upgrade full magento version, i can upgrade only paypal module but again query is will it be compitable with 1.6.
