I've installed Role User Editor to allow subscribers or any other custom role to read and comment draft posts and pages (unpublished ones).
I can't manage it.
I found this topic saying allowing to view (and, they say, edit) PRIVATE posts and pages will work, but it doesn't. Draft post can be seen by a Subscriber in dashboard, but when I click on "preview", I have "this page doesn't exist" as for a non-logged viewer.
Thanks for your help.
