I've searched and browsed through countless threads here and haven't found anything about this.

I am in the process of tweaking my site and have ran into a slight problem. I was using a layout consisting of the center column and the right sidebar. I've decided to get rid of the sidebar. I also changed the background of the posts. The background consists of 2 images, one centered on top and one centered on bottom with solid background color underneath. On the main page, the posts look exactly as I want them to. However, when I click on an individual post or page, the top and bottom images in the background are not showing, just the color. I styled the background in the ATO > STYLE POSTS & PAGES > POST Container. Perhaps there is a conflict somewhere.

The url for my site is: http://www.uphereinmytree.com/

Any help would be greatly appreciated.

you have a caching plugin - you should always disable caching plugins when making changes

I deactivated the plugin, saved changes, but the individual posts / pages still are not displaying properly.

Oh, I'm using Atahualpa 3.7.9 and Wordpress 3.4.2.

What are your post page settings

I'm assuming you mean in ATO, right? This is what I have for the "Post Container," which seems to be the only problem.

margin: 0px 0px 50px 0px;
background: url(wp-content/themes/atahualpa379/images/Border-Top.png), url(wp-content/themes/atahualpa379/images/Border-Bottom.png);
background-position: center top, center bottom;
background-repeat: no-repeat;
background-color: #dbddde;

The URL is improper, try fully qualifying it

Annnd that was easy. Thank you for your help. Always appreciated. I actually feel quite dumb right now.
