For some reason I can’t set my homepage and several other pages as full width. It was full width till I changed the Page Settings to select a sidebar. I have since changed it back. But I have lost my full width pages. All boxed. Even if I go inside the individual page and scroll to the bottom and select ‘Full width page’ I still have a boxed wrapper for the page making a mess of it. I have cleared the cache several times. Also took all the widgets out of the Page Sidebar Area.
