Have you opened any support ticket with WHMS regarding this? What was their reply?

Which PHP version and web server are you using?

Hi @Net20,

This error means that a payment gateway is missing.

Please check the Billing > Payments > Payment Gateways > Manage Existing Gateways tab.

You should see an error for the missing gateway, so you know which one to re-upload.
