Lynne, your answer cleared the path and solved my problem.

I use a template, which did a hard mod, thought that the cms fetch all information within this layout, more is not what happens.
Even keeping the disabled he continued searching for the style vbcms_body_background the default layout.

Thank you for your attention in my case and I apologize for spelling errors.
