Facebook Open Graph not clearing cache
发布于 2011-04-25 08:23:07
I'm having troubles with my meta tags with Open Graph. It seems as though Facebook is caching old values of my meta tags. Old values for Attributes og:title and og:url are still used, even though I have changed them already.
I ran Lint on a page in my site, and this appeared:
Notice that there are two values for og:title and og:url, and the last one prevailed. However, The last two entries are the OLD entries that I used for this site. I am now currently using these meta tags (you can verify if you view the source of the HTML):
<meta property="og:title" content="Smart og rummelig pusletaske fra Petit Amour med god plads til alt – værdi 1.099 kr – køb nu kun 599 kr "/>
<meta property="og:description" content="Pinq.dk - Det gode liv for det halve"/>
<meta property="og:type" content="product"/>
<meta property="og:url" content="http://pinq.dk/tilbud/landsdaekkende/lissy/"/>
<meta property="og:image" content="http://pinq.dk/wp-content/themes/pinq/images/logo-top.png"/>
<meta property="og:site_name" content="Pinq" />
<meta property="fb:app_id" content="161840830532004" />
Why is Facebook caching og:title and og:url? Is anyone experiencing the same issue?

param fbrefresh might not be necessary as the debug tool refreshes the object without it.
It does not clear the cache whatsoever unless you use this parameter.
Untrue, adding that parameter makes no difference to the debug tool's operation - there is no reference to that parameter whatsoever in the debug tool or scraper code
There's no need to use the fbrefresh parameter, but you do need to be logged in as an admin for the FB app that owns that domain, otherwise the cache won't be updated.
I can verify that adding the fbrefresh parameter worked for me. If I shared the URL it used old data even though debugger was showing the correct data. But once I used the debugger with fbrefresh parameter then even normal shares used the correct data.
