Prevent users from writing ads in the parent category.
I created a parent category: CatONE.
I created 3 daughter categories assigning each to a specific group of advertisers:
CatA --> UserA
CatB --> UserB
CatC --> UserC
Then UserA can place ads only in CatA
UserB can place ads only in CatB
UserC can place ads only in CatC
But I have a problem: all users can place ads in CatONe. How can I avoid this?
I tried to set the Super User as the only CatONE advertiser. But this makes it so that the other Users can not create any ads.
How can I fix it?
