Изменение пароля WP
Перейдите в папку активной темы: /wp-content/themes/ваша-тема/.
Откройте файл functions.php.
В самый конец файла добавьте строку:
php
wp_set_password( 'новый-пароль', ID_пользователя );
замените 'новый-пароль' на желаемый пароль;
укажите ID_пользователя (у администратора обычно 1).
Сохраните и загрузите файл на сервер.
Откройте любую страницу сайта в браузере — пароль сбросится.
Обязательно удалите добавленную строку из functions.php, чтобы пароль не сбрасывался при каждом заходе на сайт.
