wordpress — Невозможно войти в Wp Admin — Ошибка отправленных заголовков Pluggable.php

Я не могу войти в раздел администратора моего сайта WordPress.

Я получаю эту ошибку:

Warning: Cannot modify header information - headers already sent by (output started at wp-includes/pluggable.php:1) in wp-includes/pluggable.php on line 1210

если я включаю отладку в wp_config, я получаю эту проблему здесь:

Я переименовал папку плагинов в своей папке wp-content и все еще не могу получить доступ к администратору.

Плюс я удалил все активные плагины в PHPMYADMIN из базы данных и до сих пор не могу войти в админку.

Любая помощь в этом?
