After I add/edit widgets and/or code to a page, I can't get the editor to work no matter what I do. So I have a page where the bg is stuck, and I can't remove it nor can I remove the region. I am also having trouble removing regions where I have deleted content. When I click the "edit background" button, nothing happens. I am able to drag new content just fine but that is all the front-end editor will do.
