Missing "dark-blue" class on single service page

Hello-- For some reason pages created by the Services widget for service details no longer show the white background against which most of the text is supposed to display. Checking the code in the body classes against that in the same page on the Demo site, I notice that there is a "dark-blue" class there but not in mine. Any idea what might be causing this, and what I can do about it? I had been attempting to add a left-hand menu to that page using a child theme, but gave up and have stripped out almost all the changes I can think of that might be involved. The same thing happens if I don't use the child theme at all.
