MY APOLOGIES.
The information give below proved to be inaccurate. I was confusing the member payment emails we received from PayPal, with IPN working. They were not working, so this question is invalid. Please ignore it, or preferably DELETE it!
Our old website had the PayPal IPN URL:
http://www.workingsheepdog.co.uk/?s2member_paypal_notify=1
We changed to a new domain, and changed the PayPal IPN URL to:
The (now parked) workingsheepdog.co.uk .htaccess points to yet another domain:
https://theworkingsheepdog.com - but when our members pay us, the IPN appears to be working normally. If I’d thought about this when we changed to the new domain, I’d have worried about how I was going to make it work - but that never occurred to me at the time - and it works anyway!
Is this something that s2Member takes care of, or is it down to PayPal, or what?
I’m intrigued!
