INVALID T_TERMINAL_NUMBER

I have the exact same PDF from Sage help center, so that should be the most current document. And it does say that T_terminal_number is not required, and indeed this module does not send it. So I'm not sure what's happening here. Is your Sage Payment Solutions account valid and active? Have you checked that your merchant ID & key is entered in the module properly?

Are you using the current dev version? In the latest version, the 'raw response' is not shown. It is now parsed into various fields and in the order comments you should see something like this instead:

Approved
Transaction Code: 179179
Transaction Message: APPROVED 179179
CVV Indicator: P
AVS Indicator:
Risk Indicator: 00
Reference: F2OCFlCeU0

For this module to function properly:
- A valid merchant ID and key from Sage Payment Solutions (sagepayments.com) must be entered in the Ubercart payment gateway settings.
- At least cURL and OpenSSL must be enabled to make queries and get responses.
