It depends on how this data is stored.
I need more information. Please describe it in more detail.
Thanks. Start with the most obvious, the default case. It seems that WLM has no way to set Inherit as the protection setting of existing posts. Therefore, it seems that one has to edit each post manually, even when the category of the post is set to be protect es by a membership level. I have some 300 existing posts.
I want to know how it is stored, how taxonomy and or meta data?
What do these settings look like on the post side?
Thanks for your interest. The database records for the access control seem to be as in https://d.pr/i/ClBjmK in the wlm_contentlevels table. It seems that the record that does not say Protection should have the Level_Id in that field. Am waiting for clarification from Wishlist Member support.
I think this plugin will not work for you
This is the post(post type) editor, and this plugin only edits those values that are stored on the post side(taxonomies/meta data)
