How can I add the ability to control who can create child pages?
Currently, the WordPress default is that only administrators can create child pages. Other users, even those with the ability to edit and publish pages, cannot choose a parent page for the page they are editing.
I tried adding "Create child page" and "Create child page" capabilities, but these seem to have no effect.
Secondary question: How do I remove those two capabilities I added that have no effect?
Thanks.
