我刚通过编辑主题breadcrumbs代码修复了这个问题breadcrumbs数组中缺少url行

else if ( is_tax('ranna_recipe_category') ){
            
            $terms = get_the_terms( get_the_ID(), 'ranna_recipe_category');
            echo "<script>console.log('" . json_encode($terms) . "');</script>";
            
                                     
            if ( $terms && ! is_wp_error( $terms ) ){
             
                $draught_links = array();
                echo "<script>console.log('" . json_encode($draught_links) . "');</script>";
                
                foreach ( $terms as $term ) {
                    $breadcrumbs[] = array(
                       //Adding this line solve th problem
                        'url'  => $home_url .  $term->slug,

                        'name' => $term->name,
                    );
                } 
            }
        }
