HELP - websites gone in ispconfig
I have just noticed after a failed upgrade to ispconfig, all my websites are missing. Well, actually the ispconfig installed on the SECOND attempt, but it sort of did a fresh install. When I go into ispconfig admin - everything is there as it should be - all the websites, users etc. Webmail works perfectly BUT, when you go to the users website in a browser - you just get the SHARED IP page - welcome message.
Obviously, the 'pointer' file in ispconfig is messed up. I have had a look at httpd.conf, but can't find it. PLEASE can someone urgently tell me how to let ispconfig see all the existing websites again?
