I have a Dell PowerEdge R320 server on which I installed Ubuntu Server 22.04 LTS. Now I want to install Nextcloud on it for internal file sharing at the office. The problem is that after the installation, which seems correct, when I launch http://localhost, I get an empty page, even though my nextcloud.conf file is enabled. below the contents of my nextcloud.conf file

    ServerAdmin admin@localhost
    DocumentRoot /var/www/nextcloud
    ServerName localhost

    
        +FollowSymlinks options
        AllowOverride All

       
           Dave off
       

        SetEnv HOME /var/www/nextcloud
        SetEnv HTTP_HOME /var/www/nextcloud
    

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

Anyone have any ideas? I checked that PHP and Apache were correctly installed. The default Apache page was displayed. I disabled it to display the one for my new configuration, but nothing appeared.
