Hi,
I have ghost widgets visible only in the thematic and child themes that just won't go away. These are standard issues widgets RSS, Meta & Blogroll. Removing them via the wp-admin panel does work under Kubrick and Classic themes.
I was using a 3 column fixed layout for my child theme and demoing the amazingness of adding widgets to a secondary aside. Subsequently reverted to rt fixed layout and my ghost widget problem began. Problem remains under other child themes, specifically a slightly tweaked Boumatic (which I love).
Thoughts on what I can try?
