WordPress MU

Hi all, I've got http://sustainablegators.org running on WordPress Mu. It's a custom theme I designed. The admin blog works fine as you can see; but user blogs don't resolve. See: http://test.sustainablegators.org/

The theme is apparently not the issue, since using other themes (including the classic theme) does not solve the problem.

Any idea what the issue might be? Thanks a bunch.

Read the installation instructions and turn on DNS wilcards because that subdomain does not even resolve.

Thanks, SteveAtty. It works now.

What I did was go into my HostGator CPanel and created a subdomain called "*" (no quotes). That solved the problem.
