Since we've upgraded to xf2, we're getting the following notification from paypal:
We're using "User upgrades"
Anyone facing this issue after the upgrade?
What should I check, where should I look to fix it?
I have a problem with the Payment Provider configuration of Paypal. I want to create IPN with my PP Account. But if i want to access my payment_callback.php i get an 403 in my logs and the site isn't loading. All other php files works perfectly. Only the access to payment_callback.php...
