I received email from paypal saying... " Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing: https://mywebsite.com/amember/payment/paypal/ipn 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." Appreciate any idea to resolve this. Thank you.
