Display Page Categorie on LP

Hi,

I have Roseta on staging environment, trying to work out whether it will work for our needs.

Our site is mainly bases on Pages, not Posts. I added some code to the child-theme functions.php to add categories to pages in the hope this would work to display pages on the Landing Page elements:

function add_categories_to_pages() {
register_taxonomy_for_object_type( ‘category’, ‘page’ );
}
add_action( ‘init’, ‘add_categories_to_pages’ );

The theme doesn’t seem to recognize it though. Are they any code alterations I can make to the theme files that would help?

Thanks
