    # 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.

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

<p>wsgi.py on mywebsite</p>

<pre><code>import os
from django.core.wsgi import get_wsgi_application
path = '/var/www/mywebsite/website'
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "website.settings")
application = get_wsgi_application()
</code></pre>

<p>Check to make sure nothing is listening on port 80. I'm not sure what the <code>website.settings</code> contains but it is possible that either this apache instance is trying to use the same port as another, or something else is running on port 80. (this is the default port). You can check if something might be using the port with <code>netstat -tulpn | grep :80</code></p>

<p>You can alter the port of this server to avoid the collision or, stop the other process.</p>
