I've got a Drupal (4.7.2) site running on DreamHost. As usual, the mysql database for the site lives in a subdomain under the Drupal site's domain; let's call it mydb.example.com. When I try to go to the site and presumably get to the phpMyAdmin install that lives there, Drupal somehow gets its hands on the request and returns a "Page not found" page (a Drupal-generated page with this message, that is -- not a server-level 404 message).
Arggh. Have I mis-configured something somewhere? Any advice?
