Hello again, I have to bring forward this topic.
I have done since my last post a lot of tests, but I've still problem with paypal IPN; when an user makes a payment, I have to set it as confirmed manually, after I've verified on PayPal the money on the account.
I've taken a look on CB Subs notifications, and in the end after COMMUNICATION ERROR I have found the error below:
$error='Error: cURL could not retrieve the document, error 28.';
$status='0';
$transaction_info='';
I'm not able to understand in what I'm wrong, I have configured PayPal gateway in CB Subs, I don't know really what to do more.
Thanks for your attention,
regards.
