    I’m a beginner in WorldPress.
    I’d like to show Related Posts.
    In the main menu I have Category A, and in Category A – Subcategories A, B and C. The posts are in Category A, but they can also be present in all 3 Subcategories.
    When choosing one of the Related Posts something goes wrong and the posts from the initially chosen Subcategory don’t show correct anymore.
