breadcrumb full path

hi!
i want to show the full breadcrumb path on top of each site, but it only shows the home link and the subcategory.
i tried several plugins (eg Breadcrumb Trail, Yoast Breadcrumbs, Breadcrumb NavXT) -> all the same effect. also a code included in the header file has the same effect.

http://delusions.at/

here is the code

<?php // Breadcrumb navigation
if (is_page() && !is_front_page() || is_single() || is_category()) {
echo ‘<ul class=”breadcrumbs”>’;
echo ‘<li class=”front_page”>‘.get_bloginfo(‘name’).’‘;

if (is_page()) {
$ancestors = get_post_ancestors($post);

if ($ancestors) {
$ancestors = array_reverse($ancestors);

foreach ($ancestors as $crumb) {
echo ‘

• ‘.get_the_title($crumb).’

‘;
}
}
}

if (is_single()) {
$category = get_the_category();
echo ‘

• cat_ID).'”>’.$category[0]->cat_name.’

‘;
}

if (is_category()) {
$category = get_the_category();
echo ‘

• ‘.$category[0]->cat_name.’

‘;
}

// Current page
if (is_page() || is_single()) {
echo ‘<li class=”current”>’.get_the_title().”;
}
echo ”;
} elseif (is_front_page()) {
// Front page
echo ‘<ul class=”breadcrumbs”>’;
echo ‘<li class=”front_page”>‘.get_bloginfo(‘name’).’‘;
echo ‘<li class=”current”>Home Page’;
echo ”;
}
?>

can anybody help me?

thanks
