Debut is a premium theme and we Volunteers answering questions on this forum have no knowledge of how they are designed to operate. When you purchased your premium theme what came with that purchase was support directly from the theme designer in the Premium Theme Support Forum.
The premium themes forum is now open to all users so you can search to see if your question has been previously asked and answered there. The premium theme forums are at http://premium-themes.forums.wordpress.com/ with separate sections for each theme. http://premium-themes.forums.wordpress.com/debut/
If you are not successful when searching there is a link for the specific Premium Theme support forum for your theme under Appearance -> Themes in your blog’s Dashboard, but do note that the premium theme must be active and you must be signed in as the user who purchased it in order to see it and post to it.
