Can NOT change bg color no matter what I DO...

Help my wife had some friends build a site with ZENcart using ZenMagick and I am trying to change the bg color (heck any color) I change templates and no matter what sylesheet I edit the color and image still stays the same ??

The body bg - body {color:#303030;background:white;} in theme.css

The center column - #container {
width:770px;
margin:10px auto;
background:#F6F8F0;}

in site.css

Thanks, right after I posted some how I was able to get the DEMO zenmagick template to work as you see white bg and all woohoo !! I still have issues with other templates defaulting to what the others folks designed. I am going to go from here now that I have it changed...
