[SOLVED] Problems configuring comments

I'm trying to configure changes to the Comment box (the box that contains a comment) and the Comments Above box (the one liner box that says "x comments to "comment name").

Many of the configuration options for comments don't seem to work. Here are a couple examples:

1. Changing the color in <<Comments / Style and configure Comments / Regular comment background color>> has no effect. The background color of the Comment box does not change. It is now set to light blue (e8e9f4) and it is beige (eeeae1) in the blog page. See link below.
   
2. Changes to <<Center column / Next-Previous navigation / Style the Comments Above box>> have no effect. The background color is also set to light blue and it is white in the blog page.

URL of the blog (work in progress): http://julesgobeil.com/wordpress/

Is there a switch or another configuration option that blocks these changes ?

Using Wordpress 321 - Atahualpa 367 - ata-round theme - Windows 7 - Firefox 602

Thanks for your help
