If you have members that have signed up for recurring billing, but you have not selected a payment gateway yet, you may get the following message emailed to you:
"Recurring Billing Problem Occurred:
There is no payment gateway specified for your site.
No credit cards can be processed."
MemberGate is set up to continuously retry the billing every hour until a payment gateway has been set up or else the member who's recurring billing is trying to be processed is canceled.
To set up your Payment Gateway choose 'Payment Gateway' under 'Master Settings'.
