I just tried above but it took all the sites offline ....
I have 1 x IP shared for all vhosts.
Server IP was originally only in [Server Config] so all vhosts were set to[*] - we experienced the exact same symptoms as Iceman100
I added IP to [Server IP addresses] , now the option to select the IP for each vhost became visible.
After changing[*] to IP address on just one of the vhosts the problem was fixed BUT after a few minutes all hosts start responding with Apache default page.
Changing just the same one vhost back to[*] restored ALL the vhosts but of course the original problem is now back.
Any ideas ?
[EDIT] Just created a default site called "00000-defaultsite.tld" to ensure that its the first one alphabetically.
This seems to have worked. See - http://www.howtoforge.com/forums/showthread.php?t=58419
