Hey, I've set up a few sites by now and never had this problem before (but I'm using a new host this time.)
My 6.3 install failed the Clean URL test. I called tech support and they said to include "
RewriteEngine on" in my .htaccess file. (The Drupal install includes this out of the box, no?) The Handbook Page on Clean URL's speaks of adding "
AllowOverride All" to httpd.conf "so that local .htaccess commands will be run for your site" which I believe is an Apache config file that I don't have access to.
