so, I "installed" my paypal service now for donations. But I am not sure if it works, is there some way to test it? I am pritty unsure if it works, when I enter MYSITE/ipn.php I get these errors:
I am using ZnoteAAC-master(1.5) I tought I missed something in the config.php ... But everything looks nice there.
ipn.php:
Code:
