Ok, after making the last updates for my cobalt RAQ 4i.(the ones after the OS2) Now, I'm not be able to add any virtual sites at all.
When I hit the "confirm new site" button , it stucks on the page saying; "Saving configuration. This will take a moment..."
then nothing happens. The page stands still.
Any ideas what's going on.??
Thank you,

Solved, here is the solution if anybody interested...

login by telnet/ssh as admin, su to root. and do:
/usr/sbin/grpck. It will prolly find a user that is binded to a group, and
that user doesnt exist in de passwd anymore. it will find the error, and
ask you to fix it.
after that do: rm -f /etc/.pwd.lock and rm -f /etc/locks/*
after that it should be working again.
