Nếu box chat không hoạt động thì kiểm tra lại xem đã nhúng hQuery vào template chưa (hầu hết các templates đều không có), chưa thì nhúng jquery sau vào ngay trên đoạn code bước 3.

Bạn có thể xem mẫu box chat đã được cài ở trang

Một chú ý nhỏ, ngoại trừ web bán hàng online với lượng khách hàng chính từ facebook, còn không thì không nhất thiết bạn phải cài Messenger vào
