Could someone tell me what this means and how to fix it?

Hi …

I am working on breadcumbs and the theme came with Dimox. It is working, however, when I click on a category I get this

Home ? Archive by category ‘How To Buy A Used Car’

How can I change this to get rid of the Archive by category, or does that have to stay there?

I think I found where it could be changed but I am not sure. If this is in fact where to change it

if ( is_category() ) {
$thisCat = get_category(get_query_var(‘cat’), false);
if ($thisCat->parent != 0) echo get_category_parents($thisCat->parent, TRUE, ‘ ‘ . $delimiter . ‘ ‘);
echo $before . ‘Archive by category “‘ . single_cat_title(”, false) . ‘”‘ . $after;

Could someone please show me how?

Also, I wanted to make the links darker so they would show up on the page. I went into the CSS sheet found the breadcrumbs and changed the colour codes that are there but they didn’t change over. Is there somewhere else I am suppose to go?

This side of things is totally new to me. So if I come back and sound like an idiot it’s only because I have never worked with this before, so please bare with me.

Thank you!
