This is from file
/etc/apache2/sites-enabled/000-default right after installing apache2 from repositories.
DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory>
What does that first part set up? For me this looks that DocumentRoot should be / instead /var/www allowing that
<Directory /> part to have any effect but I have to be wrong.
