I am Drupal newbie taking over a poorly documented D6 group of sites organized by sub-domains. In examining the dev.[domain].org/sites/ folder I discover folders: all, default, demo.[domain].org and [customer].[domain].org and each folder has its own settings.php?
For example, /default/settings.php allows me to configure-or-edit the 'site_name' => and $db_url and $base_url. The $db_url works.
while, /all/settings.php has a disabled # $base_url and a disabled # 'site_name' => yet an active $db_url that is connecting to a 'mysql://[detail]' that may or may not be an active db.
I presume folders demo.[domain].org and [customer].[domain].org in the /sites/ folder are just legacy folders left by the previous coder/hacker of the settings.php used in the those sub-domains.
Your thoughts and answers will be gratefully consumed.
Thank you, Steve
