php - Wordpress breadcrumbs issue -

i have breadcrumb in website that's not working properly. when go product like

equipment» products» railing» heavy railing» waterproof» superrail 2000

it shows me breadcrumb should. when same product through "non-waterproof" instead of "waterproof" shows me same breadcrumb (so basicly, follows 1 category).

i wanted check in settings of breadcrumb plugin, shows me message "your settings out of date. migrate now.", , supervisor has adviced me not "migrate" it.

does have solution uses either plugin or custom code works multiple categories?

edit:

i'm working wp 3.6, i'm not allowed update. url looks http://www.website.com/product/asl6109t32/, means can't use url generate breadcrumb.

if may, here nifty code snippet creating breadcrumb navigation, place in theme'sfunctions.php file:

/***********************************************************  * wsf_breadcrumbs() - shows breadcrumbs in template  ***********************************************************/   function wsf_breadcrumbs( $sep = '/', $label = 'browsing' ) {        global $post, $front_page;       // not show breadcrumbs on home or front pages.      // return      if((is_home() || is_front_page()) && (!$front_page))         return;        // create constant separator, space padding.       $sep = ' ' . $sep . ' ';      echo '<div class="breadcrumbs">';     echo $label;     echo wsf_make_link( home_url(), 'home', get_bloginfo('name'), true ) . $sep;      if(is_single()) {       the_category(', '); echo $sep;      }      elseif (is_search()) {         echo 'search results - ';     }      elseif (is_404()) { //wordpress bug         echo 'error 404 (page not found) ';      }     elseif (is_author()) {         echo 'articles posted author ';     }     elseif (is_tag()) {          echo 'posts tagged ';     }     elseif (is_year()) {         echo get_the_time('y');     }   elseif (is_month()) {         echo get_the_time('f').' ('.get_the_time('y').')';     }      elseif (strstr($_server['request_uri'],"wp-login.php")) {         echo 'administration panel';     }       elseif(is_page()) {           $parent_id = $post->post_parent;           $parents = array();           while($parent_id) {                   $page = get_page($parent_id);           $parents[]  = wsf_make_link( get_permalink($page->id), get_the_title($page->id) ) . $sep;                   $parent_id  = $page->post_parent;           }           $parents = array_reverse($parents);       foreach($parents $parent) {          echo $parent;       }     }      // wordpess function echoes post title.     the_title();     echo '</div>';   }   /*------------------------------------------------------*/ /* create breadcrumb navigation /*------------------------------------------------------*/ /***********************************************************  * helper functions template coding  ***********************************************************/   function wsf_make_link ( $url, $anchortext, $title=null, $nofollow=false ) {      if ( $title == null ) $title=$anchortext;      $rel = ($nofollow == true) ? ' rel="nofollow"' : $rel = '';        $link = sprintf( '<a href="%s" title="%s" %s>%s</a>', $url, $title, $rel, $anchortext );      return $link;    }    /*------------------------------------------------------*/ /*------------------------------------------------------*/ 

then, in footer.php file, invoke function this:

<div id="breadcrumb">  <?php wsf_breadcrumbs('','') ?>   </div>
