AVS Mismatch, International Addresses, Authorize.net & Change of Payment Gateway

Hey all,

I installed PMP to a site that uses recurring monthly payments for an online course that people world wide are registering for today. I’m using Authorize.net as the gateway. Many international (I’m US based) people are emailing me saying they are receiving an AVS mismatch. Someone from the US registered successfully, just for the record. Doing some research on my own to solve this, first, I went to github and installed the plug-in “pmpro-international-adresses” and, even after installing, I’m receiving similar emails. How can I resolve this? I have a few ideas:

1. Change to a payment gateway that will work- I’m eyeing PayPal Express, but the downside is that we want people to pay with their credit cards, not PayPal accounts. (Which actually leads me to another question: If I change the payment gateway, what happens to those recurring payments that registered through the previous gateway?)

2. I found some addition code on github at this link: https://gist.github.com/strangerstudios/1212479

I’m likely going to put that in the functions file to see what happens, but I still have a lot to learn in terms of code and WP development, so I want to check if anyone else has a better solution.

Please advise as soon as you can, it would be ideal to find a solution today.

Thanks so much in advance,

LOR
