This is backend.
How would I go about removing the WPUF Post Lock fields injected into a user profile.
I used my usual methods of remove_action but am I missing something.
Have I got the global correct?
It's not coming from WPUF_Subscription class, but from WPUF_Admin_Posting_Profile. Removing any action within a class is always a trouble. If the WPUF_Admin_Posting_Profile was in a global variable, you could do that easily using your method. But as it's not in any global variable, that would be very difficult to do.
