This is a great tutorial and it totally worked for me. Now I've got a multi-site set up where I have sub directories (named example1.com, example2.com, etc) under the main "sites" directory. But I cannot seem to access those sites, and I was able to before. Of course this was back when my drupal files lived directly under the publi_html dir and not in a sub dir under the root. But now when I move drupal to a sub dir, I can no longer access my other sites.

I have even made the database line adjustments to code in the settings.php files for each site dir. How does one go about having a multi-site installation of drupal and still have everything under a sub dir. I would greatly appreciate your help, thanks.

Best, Bao
