我使用下面的代码，只是标准的 FBML 之类的按钮，安装了它，工作正常，然后我更改了元描述，但按钮仍然拉旧的而不是新的。
我已经刷新了数据库，因此旧的描述不在我的网站或系统上的任何位置。
<div id="fb-root"></div><script src="http://connect.facebook.net/en_US/all.js#appId=262424633777014&xfbml=1"></script><fb:like href="" send="false" width="400" show_faces="false" action="like" font="verdana"></fb:like>
我在其中一个答案中读到，一旦首次共享，FB 就会将其存储在自己的数据库中。
对于如何解决这个问题有什么想法，或者 Facebook 是否会在一定时间后更新？
顺便说一句，共享此按钮也发生了类似的情况，旧样式按钮拉动旧元描述，新按钮拉动新元。
令人困惑的是，旧数据肯定不再出现在我的网站上。
任何提示、答案都非常感谢。
I am using the code below, just the standard FBML like button, installed it, was working fine, then I changed the Meta description, but the button still pulls the old one rather than the new one.
I have flushed the database, so the old description isn't anywhere on my site or system.
<div id="fb-root"></div><script src="http://connect.facebook.net/en_US/all.js#appId=262424633777014&xfbml=1"></script><fb:like href="" send="false" width="400" show_faces="false" action="like" font="verdana"></fb:like>
I've read in one of the answers that FB stores this in their own database once it is first shared.
Any thoughts on how to solve this, or if Facebook updates after a certain time?
Incidentally, something similar was happening with a Sharethis button, the old style button pulls the old meta description and the new one the new meta.
The baffling thing is the old data is definitely no longer on my site.
Any hints, answers greatly appreciated.

在您的页面上运行此工具：http://developers.facebook.com/tools/debug
将强制清除缓存。
如果您也使用开放图元标记，它将有所帮助： http://developers.facebook.com/docs /opengraph/
Run this tool on your page: http://developers.facebook.com/tools/debug
It will force clear the cache.
It will help if you are using open graph meta tags too: http://developers.facebook.com/docs/opengraph/
确实，它在他们的缓存中。它应该会在某个时候自动更新。很难说什么时候，而且如果你的页面没有被很多人观看，它可能永远不会更新（对他们来说不值得。）
It's in their cache, indeed. It should get updated automatically at some point. It's hard to say when, plus if your page is not watched by many people, it may never get updated (not worth it on their end.)
正如点赞按钮文档中所解释的那样
