当我为我的网站创建一个私有和自定义主题时，我为我想要显示的不同类型的数据创建了自定义帖子类型（并使用自定义字段添加额外数据）。

不管怎么说，由于我设法让一切都正常工作，不知何故，这些项目从管理菜单中消失了，因此我无法为我的自定义类型编辑或添加新内容。

以下是pastebin上的来源：http://pastebin.com/dmA6PQSR

       }

       return $main;
   }

帖子类型正在注册并在这个意义上起作用，它只是没有出现在管理菜单或管理栏中。它确实通过使用查询和菜单来显示。

我希望有人能帮忙，因为我已经一个多月没找到bug了-\\u-提前谢谢
