On the "dashboard' page where I compose a new post, to the right is the traditional Visibility feature where you can make the post public or private. Suddenly, I'm stuck with only Public as an option. When I click on "edit" to change it to "private" nothing happens. All was working just fine for the last few days including this feature. I'm using 2.7 Coltrane. I've uploaded nothing else in the last few days to conflict with anything. I need help resolving this . . .
