IPN from paypal is Active and membbership pro is not changing status

Hello,I'm experiencing an issue with Membership Pro's PayPal integration. The IPN is active and correctly set up in my PayPal account (I've double-checked the settings), and new registrations are being recorded. However, since about a week ago, the payment approval process has stopped working as expected.In my PayPal IPN history, I can see that PayPal is attempting to send the IPN messages and even shows multiple retries. Despite this, Membership Pro does not update the payment status, which forces me to manually verify and activate each PayPal transaction.Have you encountered this issue or have any suggestions on where to start troubleshooting? Any help would be greatly appreciated!Thanks in advance.Oscar Acosta

Hi Oscar

Maybe the server updated something (like PHP to a newer version) recently and it causes the issue?

Please go to Membership Pro -> Payment Plugins, click on os_paypal payment plugin to edit, set Use custom certs parameter to Yes

Then check it again to see if it works
