Apache дает страницу 'It works' вместо домашней страницы сайта

Мой сайт www.domainname.com загрузки apache2 страница 'It works' вместо ожидаемой домашней страницы мычавших, которая расположена в /var/www/html/moodle. Существует индексный файл index.php в каталоге Moodle, но это не взято по умолчанию. Если я перехожу в www.domainname.com/moodle домашняя страница сайта прибывает. Конфигурационный файл /etc/apache2/sites-available/domainname.conf включен. Как решить это?

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    ServerName www.domainname.com
    ServerAlias domainname.com

    # For most configuration files from conf-available/, which are
