You changed the values for your Open Graph tags on your website but Facebook still shows an old (obviously cached) version of your shared or liked page?

We came across that problem and here is what you can do:

1. Add query parameter to liked/shared URL

One way is to simply change the URL of your page by adding a URL query parameter e.g. ?v=1
This means you’ve got to share http://www.mypage.com/fbapp/?v=1 instead of http://www.mypage.com/fbapp/

2. Use Facebook URL Linter (now called debugger)

Facebook offers the possibility to display the values it extracts from your page. This values are used in the timeline when a friend likes or shares your page. Facebook seems to refresh the cache if you submit your page’s URL to the debugger.

This is what a link looks like in Facebook’s debugger:

And this is what it looks like in your newsfeed:
