Facebook 共享按钮：在FB上发布错误的元数据

问题：当有人使用“我的博客”中的“共享”按钮时，它会以以下方式在其页面上发布：

西雅图的[共享者姓名]通过[错误姓名]共享了一个链接

“via”后面的名字是一个家伙的名字，他六个月前曾是博客的开发者。在我的博客上的任何地方，或者在我能找到的任何代码中，都没有他的名字

什么值决定了显示在那里的名称？推荐人？描述我找不到答案，也找不到编辑它们的地方

通过插件社交共享工具包（）在我的Wordpress博客上使用Facebook共享按钮已经一周多了

以下是该插件的代码（注意：它包括“喜欢”和“跟随”按钮的选项）：

---

在用户部分查找他，看看他的权限是什么。我会删除他的帐户，然后把你的URL放到Facebook调试器中，重新扫描你的网站。看看会发生什么
 是的，我昨天删除了他的账户。它是否需要时间才能显示？这是我从调试器得到的：推断属性：应该显式提供'og:url'属性，即使可以从其他标记推断出值。推断属性：应明确提供“og:title”属性，即使可以从其他标记推断值。推断属性：应明确提供“og:description”属性，即使可以从其他标记推断值。推断属性：即使可以从其他标记推断出值，也应显式提供“og:image”属性。如何提供这些。。。？
