Why is Pay Online 'grayed out' (not available as an option) in my payment page setup?

HOW-TO:

If you haven’t already done so, add a payment gateway in your overall application setup of EventsAir.

In Event Selection screen

1. Look under Application Setup for External Connections

2. Select E-Commerce Gateway

3. Select plus icon to add your gateway

4. Choose carefully according to your financial/bank set up

Then, in your event, set up the payment gateway connection.

7. For E-Commerce Reference, add the text you want to use as a reference

8. Save

In your event itself, by default, EventsAir is able to accept cash, Visa, and MasterCard in payment types. Check that all online payment types are visible and enabled for online registration.

In Setup Panel

9. Under Financial, create a Payment Type

10. Name the Payment (e.g. Mastercard)

If needed, set up other payment types here too (American Express etc.)
