Having some problems with the plugin? Here are the most common problems and how to fix them.

Plugin marks transaction as complete, but Netbilling did not process the payment.
Netbilling will reject all payments unless the IP accessing your account is in the “Trusted Static IP Addresses Allowed to originate Direct Mode transactions”. Make sure you have the correct IP address/addresses in that list. You may need to check with your hosting provided for this additional information. Reach out to your account representative to double check the reason for the rejected transaction. They can also provide the IP that attempted to access your account, double check it against your hosting provider.

Transactions are not working.
Check that your Account ID is correct.
