I have a Drupal 6 site that is correctly returning site content (like the home page), but if you look at the response headers every page has a 404 header, instead of a 200.

Things I've tried:

1. Rebuilt the node access table  /admin/content/node-settings/rebuild
2. Cleared cache
3. Run update.php

Any ideas on what might be causing this?
