Remove CPT name from permalink but add %category% instead
You have to set “hierarchical” => true in order to get %category% and %subcategory% to display: “rewrite” => array( “slug” => “producten”, “with_front” => false, “hierarchical” => true ), Don’t forget to flush permalink settings by opening settings → permalinks and save.
