Clear out end dates for active subscriptions since the subs are managed by the gateway.

pmpro_clear_enddates.sql

# oops I had PMPro setup with recurring subscriptions AND expiration dates
# I really didn't need the expiration date because the subscription is managed by the gateway
# if payment fails, the gateway will try again based on its settings
# and when the gateway gives up, it will tell PMPro through IPN/webhook to cancel the subscription
# If I have expiration dates setup for recurring subscription, PMPro is going to cancel those subscriptions
# whether they pay or not. So I need to edit the level and remove the expiration date AND
# run this script to clear out the end dates for active subscriptions.

# BACK UP YOUR DATABASE FIRST

# Note: Your DB prefix may be something other than wp_, change the query to reflect that.
UPDATE wp_pmpro_memberships_users SET enddate = '0000-00-00 00:00:00' WHERE status = 'active';

# If you have multiple membership levels and only certain levels need to be cleaned up, use a query like this.
# Ignore the query above and change the membership_id to what you need and note the DB prefix again
UPDATE wp_pmpro_memberships_users SET enddate = '0000-00-00 00:00:00' WHERE status = 'active' AND membership_id = 1;
