Yes.
It was default at “Inherit” (whatever that is) and I have tried both right and left sidebar, 250 px width, and nothing changes from the way it is laid out now. It will remove the sidebar completely when I choose full page layout, but I want the widgets on the side to advertise my books and such.
After the last update, everything reset to defaults (which I wasn’t too happy about in the first place), but I have tried everything I know to keep the sidebar from dominating the page and nothing works.
