I received an email titled "PayPal Instant Payment Notification Warning" which contains the following information: "Please check your server that handles PayPal Instant Payment "Notifications (IPN). IPNs sent to the following URL(s) are failing: https://www.******.com/ext/modules/p...al_ipn/ipn.php. 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."
I have been using the PayPal IPN module for several years and did not change anything. Did Paypal change something on their end? Has this always been an issue and PayPal is just becoming aware of it, etc? I do have trouble with customers being able to return to my "success" page, but any fixes seemed to make things worse and/or cause issues with other payment modules so I just left it alone as I get the order. Does that have something to do with it? (I am working on getting moved over to RC4 so I wasn't in a hurry to fix that problem either). Any one else have this isssue? -Thanks.
