当尝试单击自定义分类法的“添加新设备类型”按钮时，它只是将DOM元素上移到条目列表中，而无法添加实际的术语。这是我的分类代码：

  $labels = array(
    \'name\' => _x( \'Equipment Types\', \'taxonomy general name\' ),
    \'singular_name\' => _x( \'Equipment Type\', \'taxonomy singular name\' ),
    \'search_items\' =>  __( \'Search Equipment Types\' ),
    \'all_items\' => __( \'All Equipment Types\' ),
    \'parent_item\' => __( \'Parent Equipment Type\' ),
    \'parent_item_colon\' => __( \'Parent Equipment Type:\' ),
    \'edit_item\' => __( \'Edit Equipment Type\' ), 
    \'update_item\' => __( \'Update Equipment Type\' ),
    \'add_new_item\' => __( \'Add New Equipment Type\' ),
    \'new_item_name\' => __( \'New Equipment Type Name\' ),
    \'menu_name\' => __( \'Equipment Type\' ),
  );

  register_taxonomy(\'equipmenttype\',array(\'powerequipment\'), array(
    \'hierarchical\' => true,
    \'labels\' => $labels,
    \'show_ui\' => true,
    \'query_var\' => true,
    \'rewrite\' => array( \'slug\' => \'power-equipment\' ),
  ));

我没有使用任何自定义的管理JavaScript，我启用的唯一插件是Akismet和Wordpress导入器。此外，标准类别分类法不会出现此错误。
