Not compatible with Add categories to pages plugin

Changed from categories to tags and it works now. I think the problem lies with the other plugin; Add Categories to Pages.

To add categories (and tags) to pages, I just add this to my functions.php and so far (to my knowledge) not conflicted with anything on some quite plugin-heavy sites ??

// Add categories and tags to pages
function add_taxonomies_to_pages() {
	register_taxonomy_for_object_type( 'post_tag', 'page' );
	register_taxonomy_for_object_type( 'category', 'page' );
	}
add_action( 'init', 'add_taxonomies_to_pages' );
	if ( ! is_admin() ) {
	add_action( 'pre_get_posts', 'category_and_tag_archives' );
	}
function category_and_tag_archives( $wp_query ) {
	$my_post_array = array('post','page');
 
	if ( $wp_query->get( 'category_name' ) || $wp_query->get( 'cat' ) )
	$wp_query->set( 'post_type', $my_post_array );
 
	if ( $wp_query->get( 'tag' ) )
	$wp_query->set( 'post_type', $my_post_array );
	}

(On occasion I’ve found this really helpful in combo with LCP, which is why I’m posting here, though somewhat marginal relevance to this plugin.)

Hope that’s helpful.
