Hi!

I've made a group called 'SuperAdmin'

I've defined two members, they're both [wp-admins]

I've made a category superadmin which I have restricted on all roles, then assigned  'Category Manager' and 'Post Editor' (selected and sub-cats) for the group SuperAdmin

Now any post I make in this category is only visible and edible to SuperAdmin members, nice!

However  [wp-editors] can still see and edit the category. If they delete the category, naturally all of the posts becomes globally viewable/editable

I thought that by restricting category-manager and then assigning it only to a select few, I would ensure that nobody else could manage that category, but apparently I am wrong.

Is this because [WP-Editors] already have the 'manage posts' capability built-in, and then FORBIDDEN+ACCESS = ACCESS?

How can I create a category that only a certain user-group (SuperAdmin) can manage?

TIA
