Я не получаю никакой ошибки, но также не получаю ни одного блога, Проблема с разбиением на страницы

Я не получаю никакой ошибки с этим кодом, но также не получаю никакого результата, он не показывает ни одного моего блога на странице. Я думаю, что HTML код неуместен. моя нумерация страниц не работает должным образом, прежде чем выдает ошибку порядка, затем я упорядочил ее по дате, и теперь она ничего не отображает и не выдает никакой ошибки, из-за которой трудно исправить
