I have searched and not found any help to this:
I am using 2.8.6 with Mystique theme and I can create pages and subpages just fine and when I edit them they have the content that I wish to see in the edit window but when I view the subpage it only shows the contents of the parent.
If for example I make "page1" with contents "this is page 1" and then make subpage "child1" to page1 with contents "this is child 1", if I try to view child1 it shows "this is page 1"
The navigation shows correctly in the theme with menu in the header and drop down menu for the subpages. I have tried this with a couple different themes and they do the same thing.
