I have just loaded a new box with openSUSE 12.3 + Webmin + Virtualmin gpl (all latest code) + Virtualmin template
I used the Virtualmin Check Configuration and sorted out any issues that I had. (typically software needed I had forgotten and turning off SUexex in server templates).
I now run the configuration checker and I have the final line " ... your system is ready for use by Virtualmin"
If I now try and open Virtualmin all I have is an empty page with the text
"No Virtual servers have been created yet"
I can get back to the usual starting page with "Re-Check ... , Manage enabled .. and Edit Server..." by making a single change in Module Config.
I've really grown used to Suse and like it a lot, I'd to have to change but if I do have to is there any particular one I should consider.
p.s. I've never seen this issue before and it's my third suse box I am building.
