Go to admin Appearance -> Widgets and place widgets into “Sidebar Widget Area.””
stuck in my sidebar. Every time I mention it to my programmer he says something that tells me he is the only one who can really change it–as if it’s deeply embedded in the coding or something. http://healingpathfargo.com/massage/
