class description_walker extends walker_nav_menu {    function start_el(&$output, $item, $depth, $args )   {        global $wp_query;        $indent = ( $depth ) ? str_repeat( "\t", $depth ) : '';         $class_names = $value = '';         $classes = empty( $item->classes ) ? array() : (array) $item->classes;         $class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item ) );        $class_names = ' class="'. esc_attr( $class_names ) . '"';         $output .= $indent . '<li id="menu-item-'. $item->id . '"' . $value . $class_names .'>';         $attributes  = ! empty( $item->attr_title ) ? ' title="'  . esc_attr( $item->attr_title ) .'"' : '';        $attributes .= ! empty( $item->target )     ? ' target="' . esc_attr( $item->target     ) .'"' : '';        $attributes .= ! empty( $item->xfn )        ? ' rel="'    . esc_attr( $item->xfn        ) .'"' : '';        $attributes .= ! empty( $item->url )        ? ' href="'   . esc_attr( $item->url        ) .'"' : '';         if($depth != 0)        {                  $description = $append = $prepend = "";        }          $item_output = $args->before;         $item_output .= '<a'. $attributes .' class="external">';         $item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->id );         $item_output .= '</a>';         $item_output .= $args->after;          $output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );                      if ($item->menu_order == 1) {             $classes[] = 'first';         }          } } 

the problem wordpress doesnt show errors. have wordpress 3.8.1 , havewp_debug` set true.

the first error seems fixed changing line: function start_el(&$output, $item, $depth = 0, $args = array(), $id = 0). second error have change $item_output = $args->before; $item_output = $args['before']; cause error:

fatal error: cannot use object of type stdclass array in /home/codetoco/public_html/wp-content/themes/quins/functions.php on line 338

why getting error me not? how can fix errors?

the second error have change $item_output = $args->before; $item_output = $args['before']; cause error:

fatal error: cannot use object of type stdclass array in /home/codetoco/public_html/wp-content/themes/quins/functions.php on line 338

its because $args object , not array need use -> instead of []
