Hi,
it would be better to leave it enabled, if you prefer to disable it as you might be using the taxonomy only, then make sure you register the advert_location taxonomy in your theme functions.php file or in the plugin with code snippets
add_action( "init", function() {
$labels = array(
'name' => _x( 'Locations', 'taxonomy general name', 'wpadverts-mal' ),
'singular_name' => _x( 'Location', 'taxonomy singular name', 'wpadverts-mal' ),
'search_items' => __( 'Search Locations', 'wpadverts-mal' ),
'all_items' => __( 'All Locations', 'wpadverts-mal' ),
'parent_item' => __( 'Parent Location', 'wpadverts-mal' ),
'parent_item_colon' => __( 'Parent Location:', 'wpadverts-mal' ),
'edit_item' => __( 'Edit Location', 'wpadverts-mal' ),
'update_item' => __( 'Update Location', 'wpadverts-mal' ),
'add_new_item' => __( 'Add New Location', 'wpadverts-mal' ),
'new_item_name' => __( 'New Location Name', 'wpadverts-mal' ),
'menu_name' => __( 'Locations', 'wpadverts-mal' ),
);
$args = array(
'hierarchical' => true,
'labels' => $labels,
'query_var' => true,
'show_ui' => true,
'rewrite' => array('slug' => 'advert-location')
);
register_taxonomy(
'advert_location',
apply_filters( 'wpadverts_mal_register_taxonomy_post_type', array( 'advert' ), 'advert_location' ),
apply_filters( 'wpadverts_mal_register_taxonomy', $args, 'advert_location')
);
} );
