Очевидно, что он отлично работает с двумя выпусками .1. Он не показывает избранные изображения.2. Изображения на боковой панели под популярным пост-виджетом также не видны.
Мне нужна помощь, чтобы понять это.Моя цель - загружать изображения, чтобы ускорить загрузку страницы.Если есть какой-либо другой метод / код, пожалуйста, дайте мне знать.
Заранее спасибо.
