WordPress MU

Installed the nightly version wpmu-2007-03-02.

Got it up and running.
But new blogs created all did not have the right path to the default graphics.

For example, login screen : cannot see the image of wordpress
also visual editor : not working

both in IE and firefox.

Is it a problem with the path settings or my htaccess?

Sorry to bother you guys.

But I found the solution:
my host is actually had "prevent hot linking" on.

Now all I have to do is ask them to allow subdomain to use the images.

Gotta admit that that's a strange cause for that to be occuring.
