 * Hi,
 * The last two projects I’ve used the Breadcrumbs plugin with, have given me the
   following error with my archives template :
 * **Strict Standards: Only variables should be assigned by reference in /Applications/
   MAMP/htdocs/sitename/wp-content/plugins/breadcrumbs/yoast-breadcrumbs.php on 
   line 187**
 * Both projects have been built using the Underscored starter theme and I haven’t
   made any major changes to the archives template file that comes with the Underscores
   package.
 * The message only displays when I have WP_DEBUG enabled.
    I also get this message
   on the Breadcrumbs settings page (sidebar) **Notice: clean_url is deprecated 
   since version 3.0! Use esc_url() instead**
 * I just disable WP_DEBUG once the site is live and it’s okay but it would be great
   to completely solve this.
 * Any help is much appreciated!
 * Thanks,
 * Herman
