Your taxonomy registration in your example is showing this:
function insurance_all_category(){
$labels = array(
'name' =>_x( 'Insurance all category', 'taxonomy general name' ),
'singular_name' => _x( 'Category', 'taxonomy singular name' ),
'search_items' => __( 'Search Category' ),
'all_items' => __( 'All Categories' ),
'parent_item' => __( 'Parent Category' ),
'parent_item_colon' => __( 'Parent Category:' ),
'edit_item' => __( 'Edit Category' ),
'update_item' => __( 'Update Category' ),
'add_new_item' => __( 'Add New Category' ),
'new_item_name' => __( 'New Category' ),
'menu_name' => __( 'Categories' ),
);
register_taxonomy('insurnce_all_categories', array('insurance_all'),$args);}add_action('init','insurance_all_category');?>
and needs to be this:
function insurance_all_category(){
$labels = array(
'name' =>_x( 'Insurance all category', 'taxonomy general name' ),
'singular_name' => _x( 'Category', 'taxonomy singular name' ),
'search_items' => __( 'Search Category' ),
'all_items' => __( 'All Categories' ),
'parent_item' => __( 'Parent Category' ),
'parent_item_colon' => __( 'Parent Category:' ),
'edit_item' => __( 'Edit Category' ),
'update_item' => __( 'Update Category' ),
'add_new_item' => __( 'Add New Category' ),
'new_item_name' => __( 'New Category' ),
'menu_name' => __( 'Categories' ),
);
//new code
$args = array(
'labels' => $labels
);
register_taxonomy('insurnce_all_categories', array('insurance_all'),$args);}add_action('init','insurance_all_category');?>
