I know the theme hasn't blocked them, because it brings up Block Widgets until you install Classic Widgets. But even then, upon theme update, the widget content gets shuffled around and reassigned, and I'm unable to save them even if I get them reorganized - I get an error that says "There was an error. [object Object]" I didn't see anything in server php error log directly related to this. I'm waiting on the theme developers to look into it a little bit more.
