I recently setup a new merchant account, but none of the donation forms linked to that account will allow me to enable ACH or PayPal payment types. Any donation forms using my other merchant accounts work just fine.
Whenever we setup a merchant account, a gateway needs to be set for credit card, ACH, and PayPal payment types as these may all use different gateways. If you do not have the option to use one of these payment types, it is likely that only the credit card gateway was set. Please contact support and reference this solution ID to have that fixed for you.
