I'm trying to set a moodle server up on an Ubuntu box, which already serves Plone & Trac via Apache.

In my Moodle config I have $CFG->wwwroot = 'http://www.server-name.org/moodle'

The configuration below works fine for the first two, but when I visit www.server-name.com/moodle I get:

Incorrect access detected, this server may be accessed only through "http://xxx.xxx.xxx.xxx:8888/moodle" address, sorry

It then forwards to the IP address, where Moodle functions fine.

What am I missing to get the server name approach working correctly?

Apache Config follows:

LoadModule transform_module /usr/lib/apache2/modules/mod_transform.so
Listen 8080
Listen 8888

Include /etc/phpmyadmin/apache.conf

<VirtualHost xxx.xxx.xxx.xxx:8080>

  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>

  ProxyPreserveHost On

  <Location />
    ProxyPass http://127.0.0.1:8082/
    ProxyPassReverse http://127.0.0.1:8082/
  </Location>

</VirtualHost>

<VirtualHost xxx.xxx.xxx.xxx:80>
  ServerName  www.server-name.org
  ServerAlias server-name.org
