I have a serious issue with the IPN on my membership 2 Pro plugin.
We've had Membership 2 Pro set up on our site for a while. We have multiple subscribers with subscriptions using the Paypal standard gateway. I recently migrated our site to a new URL. It's a direct clone and the user's memberships are still present in the plugin. I've changed the Paypal IPN listening url, and it's set up correctly (new signups are logged as successful payments) however payments on user's existing subscriptions are being logged as 'irrelevant IPN call'.
The old/existing users are not renewing their memberships and when I have the details in the transaction logs and look at the 'post data'.
The request URL is listed as 'https://www.spo*****.co.uk:80/ms-payment-return/paypalstandard' for the 'Irrelevant IPN Call'.
For the successful payments it's listed as' https://www.spo***.co.uk/ms-payment-return/paypalstandard'
