Hi Tony,
When I compare the skin to the page.html file it looks correct to me. The left side has a sort of light teal background color. The right side does not, but I believe that is because your design does not have a right column, it is better to use 3 columns in Artisteer so it will create the style for the right side as well as the left side.
Because your design only has a left column Artisteer generated this in the style.css:
.art-content-layout .art-sidebar1
{
background-color: #DFE8FC;
width: 25%;
}
but if your design had 3 columns it would also have generated something like this:
.art-content-layout .art-sidebar2
{
background-color: #DFE8FC;
width: 25%;
}
you could add that to the style-artisteer-overrides.css
or you could change to a 3 column layout in Artisteer and re-export.
I don't see how upgrading to a new version of mojoPortal has any relationship to the missing right side background color, it is a CSS issue. This is not a bug in mojoPortal.
Hope it helps,
Joe
