Apache, NameVirtualHost *:80 has no VirtualHosts

[dj_king]

Hola muy buenas. Resulta que tengo una web montada en un seedbox, la cual trabaja sobre linux.
He instalado otra app para poder crear una radio online en ella, y algo ocurrio que ya no me entra en el direcotorio web, poniendome lo siguiente:

Not Found

The requested URL /flux was not found on this server.
Apache/2.2.14 (Ubuntu) Server at 109.163.239.174 Port 80

He reiniciado el servidor Apache y me da este error:

[warn] NameVirtualHost *:80 has no VirtualHosts

Las configuraciones de /etc/apache2/sites-available/default son estas:

NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin webmaster@localhost
ServerName name of your server
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>

ErrorLog /var/log/apache2/error.log

# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn

CustomLog /var/log/apache2/access.log combined

Alias /doc/ "/usr/share/doc/"

Order deny,allow
Deny from all
Allow from 127.0.0.0/255.0.0.0 ::1/128
</Directory>

</VirtualHost>


Y de /etc/apache2/ports.conf estas:

# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
# If you add NameVirtualHost *:443 here, you will also have to change
# the VirtualHost statement in /etc/apache2/sites-available/default-ssl
# to <VirtualHost *:443>
# Server Name Indication for SSL named virtual hosts is currently not
# supported by MSIE on Windows XP.
Listen 443
</IfModule>

<IfModule mod_gnutls.c>
Listen 443
</IfModule>

No se a que es debido... Se que tiene que ser por algo de esos 2 archivos de configuración (creo) pero no doy con la tecla. Agradecería mucho algo de ayuda por favor. Un saludo
