Greetings in Jesus Christ! Thank you for this awesome plugin!
I found 1 issue and also found a workaround. What I desired to do is to enable a particular user with the WP Subscriber Role to manage 1 category. So, I went to Roles -> Categories and selected "Assign for selected and sub-categories" - then selected the user name i desired to assign - then selected "Category Manager" for the 1 category - then clicked "Update".
Then I logged into that user's WP account and there is no "Categories" link shown underneath "Posts" (bummer!).
The workaround
Before or after doing the above, go to Restrictions -> Categories and in the dropdown select "Restrict selected roles" and "for selected and subcategories" - then scroll to the bottom to the "Select / Unselect All" box and select the "Category Manager" option - then click the "Update" button.
Then the "Categories" option shows up in the user account with only the one category available to manage.
Hope this helps. Would love to know if my first scenario above should have done the same thing as the workaround from a developer perspective.
thanks!
in Christ,
Scott
