Помогите вернуть настройки nginx

Хотел добавить на другой порт еще один виртуальный хост и сбил настройки nginx. Подскажите настройки по умолчанию и в каком файле. Я запутался

/etc/nginx/sites-enabled/default
Но этот линк в итоге ссылается на /etc/nginx/sites-available/default.wb

/etc/nginx/sites-available/default.wb я этот файл изменял. Его просто скопировать, куда? Предоставьте пожалуйста конфиг
