Powered by Zen - what in the world amI doing wrong?

Hello all again.

I have followed to the letter the instructions on how to get rid of Zen Cart!, The Art of E-Commerce that appears at the top of my web browser but it won't go away.

Also how do I change the colors of the top of the boxes above categories and the center column.

My site is not really ready, just beginning the process but here is a link so you can see what I am talking about

Also I found the info once but can't find it again, how do I add a background behind the logo?

Please the path to the file with the file name that you have edited?

Open your stylesheet.css that should be in your includes/templates/smock/css folder in a plain text editor like notepad and search for #009900 - this is the color green that is currently being used and change to a color that you prefer.

In the same css file find and add a background statement similar to this:

#headerWrapper {
        background: url(../images/bg_header.jpg) repeat-x;
        height: ???px;
        }

use repeat if your image is a tile - repeat-x if it is full height but not full width - no-repeat if it is a full size image(not recommended)
