I just successfully installed a drupal multi-site with the guide from http://drupal.org/node/547860, though there is still a little problem needs to face. I created three folders in the directory sites, sites/sc.com, sites/a.sc.com, sites/b.sc.com. I start the installation with a.sc.com, and then b.sc.com. Everyting works fine, but after I installed sc.com in the browser, I can't install other subdomain sites any more. Like, I create a new empty folder sites/c.sc.com, and when I point my broswer to the URL c.sc.com, broswer will take me to the sc.com site, rather than the installation page of site c.sc.com. It seems there is a installation order to make this multi-site feature work, and I have to sart with the subdomain sites.
Has anyone met this problem before? If this is ture that I can't add other sundomain sites after the main-domain site has intalled, I'm afraid this feature has a serious shortcoming.
Any help will be appreciated. Thank you!
