I just made a basic site on a fresh 3.0.1 install and tried to export/import it using this plugin (which is linked to within WordPress admin screen).
Original Site Categories:
- Child of Foo
- - Child of Child of Foo
I put posts in all the categories, then exported the site. The Categories page of my new site created with the file looks like this:
However - it gets weirder!
Child of Foo shows up, and is checked when editing a post. It does NOT show up on my general Categories page. The link to the archives for the category work just fine. So, what is wrong with this import that the child categories don't show up on my Categories page from within the admin screen? (They DO show when listed by category widget)
(Additionally, when I use a theme that does some other stuff with the categories, Child of Foo does not show up there.)
