Bug fixing in Woocommerce subscriptions plugin

I'm running WooCommerce and my subscriptions plugin has some bugs that need to be fixed. 1. Fix subscription auto renewal - Subscription renewal date does not change to appropriate date in the future when renewal order is created, it sets renewal date for exact date and time of renewal order which is now in the past 2. Pay button not showing. Add pay button so customer can manually pay order and can check whether functionality for brief 2 is implemented. 3. Fix cancellation - When admin tries to cancel subscription from subscriptions screen, it does nothing. Admin must enter detailed subscription information to cancel a subscription. 4. Subscription start date is random for some customers. For example review subscription 7537 for Richard Ebener on live site. Subscription start date is April 18, but actually customers first order was January 20. I suspect it might be resetting start date when a customer logs in, to the date of login but not sure. Whatever is causing the issue needs to be identified, and affected subscriptions start dates resolved to first order date. I think it has been caused by the Freelancers implementing the brief. 5. When customer signs in and goes to their subscription - It says there is no active subscription even when there is an active subscription. 6. Move completed work done by a previous Freelancer from test server to live site.
