Para criar breadcrumbs wordpress em seu site copie e cole o código abaixo no arquivo functions.php do seu tema:
////////////////////////////////////////////////////////////////////////
// BREADCRUMBS
////////////////////////////////////////////////////////////////////////
function dimox_breadcrumbs() {
$delimiter = '»';
$home = 'InÃcio'; // text for the 'Home' link
$before = '<span>'; // tag before the current crumb
$after = '</span>'; // tag after the current crumb
if ( !is_home() && !is_front_page() || is_paged() ) {
echo '<div id="crumbs">';
global $post;
$homeLink = get_bloginfo('url');
echo '<a href="' . $homeLink . '" rel="home" title="' . $home . '">' . $home . '</a> ' . $delimiter . ' ';
if ( is_category() ) {
global $wp_query;
$cat_obj = $wp_query->get_queried_object();
$thisCat = $cat_obj->term_id;

$parentCat = get_category($thisCat->parent);
if ($thisCat->parent != 0) echo(get_category_parents($parentCat, TRUE, ' ' . $delimiter . ' '));
echo $before . 'Archive by category "' . single_cat_title('', false) . '"' . $after;
} elseif ( is_day() ) {

echo $before . get_the_time('F') . $after;
} elseif ( is_year() ) {

} elseif ( is_single() && !is_attachment() ) {

Para exibir o menu Breadcrumbie no site, coloque o código abaixo nos arquivos do tema no qual deseja exibir o menu. Normalmente coloco nos arquivos page.php, single.php e outros.
<?php if (function_exists('dimox_breadcrumbs')) dimox_breadcrumbs(); ?>
