Not a bug I think,
if mod_rewrite is not enabled on your server, CEO url will not work
you have to uncheck Permalinks in Admin
IF mod_rewrite is enabled on your server
and your CEO url don't work
check your .htaccess file, I guessing it's empty
-------------------------------------
And you have to delete
php_flag register_globals Off
from your .htaccess file if you have a internal server error
