Im hoping for some assistance as well.

I've been trying to get this module to speak properly with Moneris but keep getting an:

"FAILED TO IDENTIFY STORE - INCORRECT STORE CREDENTIALS HAVE BEEN SENT"

I've triple checked my PS Store ID, HPP Token, and my Gateway URL is pointed at https://esqa.moneris.com/HPPDP/index.php

On the Moneris side, set under DirectPost to 'Post' and my urls appear correct.

Note: I haven't purchased an SSL certificate for my website so unsure if that is causing problems?

Spent $300 on the Moneris 'setup' fee so really would like to get this working before scrapping. Any suggestions apart from continued reading lol ;)
