Thank you guys for getting back to me.
I am using Fedora 7.
Thank you for pointing me to the path. I tried to have a look at the log files and had no idea where they were. I'll check that out and see what's in there.
But strange as it is. I have switched to my other PC (running XP pro) and I could access Webmin on the Linux server.
If I can access my server from another computer on the network then this means apache is up and running. huh?
Now hold on a sec! ...
Yes. All websites are down except Webmin which is running under apache.
Another tip is that webmin is using SSL
if you can see the above URL, then why not the other Vhosts????
