The reason why you see the 'Offline' page in your Preview is most likely because your website is currently set to 'Offline' mode in your Site Settings. To fix that please go to Dashboard > Site Settings > Site Offline and disable this setting.

Yes that is the case but its not ideal to publish the draft, I want a preview that shows the site in its offline state. ie test mode ie not published. Having to have the site online makes the preview pointless...
