I have deleted and re-installed wordpress MU, then set it to subdomain true. Then installed WPMU dashboard. It looks ok on the network admin page, but it does not appear at all on sites that I create. I don't have any new users, nor do I have any plugins activated as this is a brand new install.
Also, after clicking around a bit, the WPMU dashboard appearance and functionality changes. It becomes text only, with no graphics and reports that I don't have any themes or plugins installed. When I try to add them, it won't offer any to me.
