 * I figured it out by reading other posts – Turn off ALL plugins and then turn 
   them back on 1 at a time to see which are compatible w/3.0
 * Thanks Forum!

 * I have and had this problem across any and ALL themes, after activating an RSS
   feed widget. I removed each and every (all!) widgets. Still had both the subject
   error plus a “cannot update header” error.
 * Another forum solved the second (header) issue,
    but still stuck with the Warning:
   Missing argument 2 for wp_widget().
 * SOLVED it by renaming (erasing) the new widget’s folder from the wp-content/plugins
   folder
