Existing Apache Virtual Servers not recognized after Virtualmin installation

Hi

I have installed newest Webmin & Virtualmin on a SuSE machine that has about 20 existing virtual servers.

Up to now Virtualmin recognizied existing virtual servers after installation and showed them in the dropdown - but not on this machine.

The .conf files are in /etc/apache/vhost.d

Server version: Apache/2.2.3

I have a similar configuration on another server - there where no problems there, Virtualmin immediately recognized existing vhosts.

The virtual servers are visible in the Apache section of Webmin - so Webmin recognizes the conf files and shows all information.

Why not Virtualmin?

Any idea?

Thanks!
