删除一些类别（不应该这样做）后，我得到以下错误

可捕获的致命错误：WP\\u error类的对象无法转换为第45行[文件名]中的字符串

这是导致错误的文件。这里有一段摘录（第45行是$output .= \'<a href="\' . $link . \'">\' . $term->name. \'</a>, \';)

   ...
  foreach($item[\'value\'] as $value) {
        $term = get_term($value, $fieldSettings[\'taxonomy\']);
        $link = get_term_link($term);

        // no option may inerrupt !
        if(!$term) {
          continue;
        }

        if(isset($formatterSettings[\'link_bool\']) && $formatterSettings[\'link_bool\']) {
          $output .= \'<a href="\' . $link  . \'">\' . $term->name. \'</a>, \';
        } else {
          $output .= $term->name . \', \';
        }
      }
    }
 ...

谢谢你的帮助！
