Paynow client payments process page

Hi,
I’m testing the Payfast payment gateway on v5.3.61-C76 self hosted.

I input the Merchant ID, Merchant Key and Passphrase.

When clicking the Pay Now on the invoice page link - it shows a form, but there are no field labels.
Where can I edit or update this?

Hi,

It may be an offsite payment gateway, what do you see if you click pay now?

It does go offsite to the payment gateway page. In which case, is it possible to then disable / hide the form on the /client/payments/process page
or on the previous page, when Credit Card is clicked, go straight to the offsite payment page?

I don’t believe it’s supported
