Hi there.
Screenshot below shows page preview prior to publishing - everything looks fine.

Page is published and then edited. Note page headers and footers are added to all our pages (via space Look and Feel).
Screenshot below shows preview of page. The header, content and footer are displayed in three columns. Is this a configuration thing? Can we turn the header and footer off the preview. Even if I make the head and footers a single character the preview still looks poor. I'd expect a preview to show the header at the top and footer at the bottom. Not left and right.

Thanks for your time
Charlie
