I have a problem using sub categories:
category 1
_category 1.1
__category 1.1.1
__category 1.1.2
__category 1.1.3
_category 1.2
__category 1.2.1
__category 1.2.2
__category 1.2.3
_category 1.3
__category 1.3.1
__category 1.3.2
__category 1.3.3
For instance, when I place a post in categorie 1.1.3, 1.2.1 and 1.3.2, and I view al posts of category 1 (root category), than the post is displayed three times.
How can I filter these out, so I only filter each post only one time?
