As discussed on another thread, since adding the IPN URL as instructed for the PayPal gateway, I receive a lot of error logs due to broadcast of details for subscriptions that were not made through the Membership 2 Pro plugin. I was told this won't cause a problem and I can just ignore them. However, I have received the following message from PayPal several times:
Please check your server that handles PayPal Instant Payment Notifications (IPN). Instant Payment Notifications sent to the following URL(s) are failing:
If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.
Thank you for your prompt attention to this issue.
What can I do to stop my PayPal account being disabled? I understand I needed to enter the IPN URL on the PayPal site so that Membership 2 Pro will know if future subscription payments for this it handles are made when the time comes or the arrangement is cancelled.
I wonder if making some sort of default invoice for these other payments might be a solution.
The people paying subscriptions directly via PayPal (actually membership fees or donations) are not necessarily members under the Membership 2 Pro system, so any invoice I create will not be assigned to a registered user.
