I installed webmin on my ubuntu 6 installation and used it to install several domains. Later I installed Virtualmin using the install script provided on the serial numbers page. The apt-get install script ran without showing errors.
When I log in to https://thesauros.com:10000 I do not get access to the normal Webmin panel but instead am shown the page labeled "System" with only the system info on it plus the normal right hand nav panel.
I am now unable to use virtualmin.
The system info shown is:

System hostname 16631-40345 
Operating system Ubuntu Linux 6.06.2 
Webmin version 1.410
