Please help the master of all that which I purpose to work.
This my code:

function jseo_breadcrumb() {

	/* === OPTIONS === */
	$text['category'] = 'Archive by Category "%s"'; // text for a category page
	$text['search']   = 'Search Result For <h1>%s</h1>'; // text for a search results page
	$text['tag']      = 'Posts Tagged "%s"'; // text for a tag page
	$text['author']   = 'Articles Posted by %s'; // text for an author page
	$text['404']      = 'Error 404'; // text for the 404 page

	$show_current   = 1; // 1 - show current post/page/category title in breadcrumbs, 0 - don't show
	$show_title     = 1; // 1 - show the title for the links, 0 - don't show
	$delimiter      = '<span style="padding: 0px 1px 0px 1px;"> ? </span>'; // delimiter between crumbs
	$before         = '<span class="current">'; // tag before the current crumb
	$after          = '</span>'; // tag after the current crumb

	/* === END OF OPTIONS === */

	if (!is_home() && !is_front_page()) {
    global $post;
    $homelink = home_url() ;
