Wrong canonical URL in Facebook cache?
This morning, I made a mistake and put in a wrong canonical URL.
<link rel="canonical" href="/skiurlaub-12833-de.jhtml"/>
I deleted the canonical URL from the page, but the like button still takes this wrong canonical URL. When I look in the debugger, I get the right information of my page.
Is there a Facebook cache which I can delete or refresh?
Using Facebook's Debug Tool clears the cache Facebook has of your page's metadata. Your page should be fine after running it through the debugger.
In my case, as difference between canonical URL and Fetched URL.
If you make both urls debugging with Facebook Open Graph Object Debuggera link , it will work.
