Pending Bookings Emails not sending

Hello-
For some reason, though we have “manually approve completed transactions” unchecked, when someone books, the following 2 problems arise:

1. After pressing submit to book for the event, the loading screen shows up and then there is NO message. So the user has no idea if they have booked or not.

2. While the booking goes into the system, it is NOT approved; it has to be approved manually. And none of the emails for the pending booking are being sent, so the admin has no idea there is a booking waiting to be approved.

I’m not sure if I configured something improperly or of it’s a bug.
