The iATS payments "modify your payments" links fail in receipts to donors. Is there a workaround?
I am on Civi 4.7.25 and iATS Payments 1.6.1
I just tested our receipt links and they work so it must be a settings issue.

I am just taking some guesses here at some possible settings


Administer > CiviContribute > iATS Payments Look for  Enable self updates to recurring ... Is this checked? If not check it and test.
I would check with iATS, Allen or Karin before changing this
Administer > CiviContribute > Payment Processors  Click edit to the left of your ACH or CC processor. Find the Site Url and Recurring Payments URL. What do you have there? I have https://www.iatspayments.com/NetGate/ProcessLink.asmx?WSDL There is another url https://www.iatspayments.com/NetGate/ProcessLinkv2.asmx?WSDL but again, I would check with iATS, Allen or Karin before changing this. You can change it and test it. If it works great, if not, just change it back. 


But if both 1 &amp; 2 match my settings, then we need to look for something else.
