通过网站重新设计更改 DNS 后，点赞按钮无法连接到 Facebook Feed
所以我刚刚在新服务器上启动了一个重新设计的网站。站点从旧服务器迁移到新服务器已经过去了48小时。我刚刚向新闻条目添加了“点赞”按钮，但由于某种原因，单击它们时它们没有显示在用户墙上。如果在下拉列表中输入评论（单击“赞”后）并单击“发布到 Facebook”按钮，则该评论会显示该页面的 URL，没有标题、没有描述文本等。我唯一能想到的就是是 Facebook 由于某种原因缓存了旧网站的 DNS，这当然会导致 URL 不可用。
有人经历过这个吗？通常“赞”按钮实施起来非常简单，但这些按钮却很顽固。
So I just launched a re-designed website on a new server. It's been 48 hours since the site migration from the old server to the new server. I just added Like buttons to news entries and for some reason they're not showing up on a users wall when clicked on. If a comment is entered in the drop down (after clicking Like) and the Post to Facebook button is clicked, then the comment shows with a URL to the page--no title, no description text, etc. The only thing I can think is that Facebook for some reason has the old website DNS cached which of course would lead to unavailable URLs.
Anybody experienced this? Normally Like buttons are super simple to implement, but these one are being stubborn.

Facebook DNS 尚未传播或者其缓存已旧。

Either Facebook DNS hasn't propagated or their cache is old.
