>That's it. Pages don't have categories and posts don't have parents.
Forget I mentioned pages all together - I get it :)
Posts don't have parents...? Clearly they do, sorry.
Why does line 145 of admin-functions.php say:
<I>if ($post->post_parent == $parent)</i> ...?
Why is there a column on the 'Manage Posts' page showing the category that each post is linked to? Those look like parents to me.
Why does each post have the ability to be associated with a category in the DB? But I no longer have a way to set that when creating a new post, nor when editing an existing post?
Why is there a section named 'Categories' on the right side of the Admin panel when writing posts?
Why is there a column on the 'Manage Posts' page showing the category that each post is under?
Getting back to my problem...
How do I change the category a post is linked to?
Why can I see a associated categories when looking at the 'Manage Posts' page, but then see nothing when on the 'Write Post' page ?
I have several categories, but none of them show up in the admin panel when writing/editing a post? The title is there, but why is that list blank?
