Paid Memberships Pro Lock Membership Level GPL Overview:

Lock a user’s membership level or lock all members of a level for a specified term (for required instalments).

How it Works

This Add On has two key uses:

1. It allows you to lock a specific user from making changes to their membership level (including selecting a new level if they currently do not have a level). This may be useful for problem members that repeatedly purchase and cancel memberships.
2. Additionally, you can use this add-on to lock a membership level for a specific term. This is useful if you want to restrict members from cancelling membership until a required number of instalment payments are made.
