在我目前的WordPress主题中，我已经为每个可能的元素实现了Microdata（使用Schema.org）。但是在我在validator.w3.org上运行标记验证后，它仅在itemprop属性上显示21个错误。
错误是：

我已经按照网站yoast.com和bloggingwizard.com实施了Microdata。这两个在W3C验证器上显示有效，但我的网站不是。有人可以帮我解决这个问题吗？
以下是验证检查的网址：

您的itemprop元素上有main，但此属性所属的父项目没有。
当您使用mainContentOfPage时，您可能希望拥有WebPage项。但请注意，此属性不能包含Blog值，它必须是WebPageElement。
因此，您可能希望从itemprop="mainContentOfPage"删除main。
