I have a question regarding recurring payments with Membership. I have my payment gateway setup as PayPal Express Gateway. Then I have three subscription plans in place, monthly, quarterly, and yearly. Under the subscription plans I have the mode set to indefinite with the monthly period set for 30 days, quarterly set for 4 months, and yearly set for 1 year. When I go to test the payment through Paypal it sets up the automatic payments, but then instantly cancels them. What am I doing wrong? Also, is there a way for me to manually delete members?
