Update:

Using the code provided:
.page #content {
background-color : transparent;
}
#primary article.hentry {
background : transparent;
box-shadow: none;
}

DID work on sub-pages – I ended up removing the #primary part of the code because the background was overpowering the text boxes, etc.

Final code used:
.page #content {
background-color : transparent;
}

This does not, however work on the main homepage. It seems just the main homepage is the problem, all others the background is now working. I don’t have a link to the site yet because it’s not live to the public.

Thanks,
