I just installed a new subdomain and everything works except the widgets page. There are no available widgets bars displaying and none of my widgets (the usual - reveal ids, akismet, etc., nothing fancy) even show up!
This is the first time that I've run into this. I did a clean install from fantastico of 3.0 and upgraded immediately to 3.01 before even inserting themes or plugins. The themes are very basic wordpress themes - three-column, widget ready, 3.0 compatible.
The widget settings don't appear no matter which theme I choose.
The theme may vary as you look at since I'm still trying to figure out which one I want to use.
