HTML Code:
<li class="cat-top"><a class="cat-not-selected catBg8" href="http://kirkgateflowers.co.uk/index.php?main_page=index&amp;cPath=8"><img src="includes/templates/template_default/images/pixel_trans.gif" alt="" width="100%" height="100%" title="£30 - £40" /></a></li>
This indicates that you have an image /buttons/english/catbg8.gif. If you do not intend to have a background image for this category, you need to eliminate this image from that folder. (Even though the bg image exists, it will not show unless you make a stylesheet declaration for it. This is a function that the code cannot automate.) Make sure that all unused images are cleared out of that folder.

You have used the "catbg#.gif" format for your heading image names. While the heading code accepts that with no problems, that kind of filename triggers a category name to be replaced if the filename matches the category cPath.

You should use the "cathead#.gif" format suggested in the readme, or something else not related to the dedicated Categories Dressing conventions.
