I got this message from PayPal recently about a site that I use for a site that includes an Expresso Store.

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.

and Store has stopped registering my PayPal payments (it lists them as pending after they have been paid). Do you know if this is a Store problem, or has PayPal changed the way it deos IPNs? I did not change anything myself.

EE 2.5.3 Store 1.6

Good idea with support on EE Stackexchange by the way!

  • On top of transitioning to PayPal Express as recommended below I would also recommend you upgrade to Store 1.6.2 as there have been many bug fixes since your version Feb 8, 2013 at 17:41

Your best bet would be to transition over to the PayPal Express gateway as it still uses the PayPal Standard account (no monthly fees) but it uses PayPal's newer API which is more reliable then requiring an IPN notification to be sent. It also allows for guest checkout and transferring address details from your site to PayPal.
