First - Excellent software! I enjoy the customization that is available which might be why I am posting the issue below. I am new to all of this and so what I am encountering is probably due to operator error.
What I would like to be able to do:
Blog B has 2 categories. 'Cars' and 'Trucks'. Category 'Cars' has two subcategories: 'Coupe' and 'Sedan'. I would like a post to 'Coupe' to only appear when the subcategory 'Coupe' is selected.
What I am getting:
A post to 'Coupe' appeas in 'Coupe' and 'Cars'.
When writing a new post I select 'Coupe' as the Main Category and deselect 'Extra' from every other box. When I publish and go back to Edit, it shows the main category to be 'Coupe' (the Extra box next to 'Coupe' is also selected) but the Post appears both in 'Coupe' and in 'Cars'.
Searching the forums for a similar question I tried to change the _admin.php file to '0' to force posts to one category but the posts still publish as described above.
