An unidentified error has occurred when deleting a category

I am developing a WordPress theme and there I used a custom post type insurance_all and a custom taxonomy insurnce_all_categories for the post type. But when I try to add a category the AJAX is not working but if I refresh the page the category is loaded. When I want to delete the category An unidentified error has occurred message show me on the top.

My custom post type is

<?php
$insurnce_all_labels = array(
    'name'                  => _x( 'Insurance all ', 'Post Type General Name', 'safest' ),
    'singular_name'         => _x( 'Insurance all ', 'Post Type Singular Name', 'safest' ),

    'name_admin_bar'        => __( 'Insurance all', 'safest' ),
    'archives'              => __( 'Insurance all Archives', 'safest' ),
    'parent_item_colon'     => __( 'Insurance all parent item:', 'safest' ),
    'all_items'             => __( 'Insurance all' , 'safest' ),
    'add_new_item'          => __( 'Add new item', 'safest' ),

    'filter_items_list'     => __( 'Filter Insurance all section list ', 'safest' ),

$insurnce_all_args = array(

    'description'           => __( 'Safest Insurance Insurance all for insurance menu', 'safest' ),
    'labels'                => $insurnce_all_labels,
    'supports'              => array('title','page-attributes','thumbnail','categories',),
    'hierarchical'          => false,
    'public'                => true,
    'show_ui'               => true,
    'menu_position'         => 8,

    'publicly_queryable'    => true,
    'capability_type'       => 'post',
);
register_post_type('insurance_all', $insurnce_all_args);

My custom taxonomy is

<?php
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_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');

Answer

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');?>
