Question

我有一个wordpress网站，我有一个博客。当我尝试在FB http://videoefekt.cz/?p=472上分享我的博文时，它会显示我主页的大拇指。我试图更改永久链接以清除，停用插件和chceck .htaccess文件，一切看起来都很好，但FB共享调试器显示我有302 HTTP重定向到我的主页，有谁能告诉我什么可能导致这个问题？

模拟Facebook抓取工具对您网站的访问权限，并在使用ipv6地址时重定向到主页。当请求来自ipv6地址时，您可能有错误配置。

curl -H "User-Agent: facebookexternalhit/1.1" "http://videoefekt.cz/?p=472" -vvvv -6
