Sir, please  check if its occurring with other modules also ?

Open a support ticket with WHMCS and with us as well. We will be happy to help you.

This error occurs after a customer has completed the checkout process and submitted payment via credit card (paypal payments pro gateway). If i make the product free in WHMCS, the error does not occur.

Even with the error, the VPS is created successfully and my customer receives his login details.
