Question

When I publish an link to my facebook page using a http post to:

https://graph.facebook.com/MYID/feed

I get the wrong image on the timeline. The title and description is correct. When I check the URL in the object debugger, everything seems fine.

For example, the following url gives me this problem:
http://www.weekmenu.nl/hollands/knapperige_slastamppot_met_gebakken_feta/

As you can see on this screenshot, the wrong image is shown in the timeline:
http://www.weekmenu.nl/wrong.png

(I’m sorry, i’m not allowed to post images or more than 2 links.. stupid stackoverflow)

It should be:
http://www.weekmenu.nl/wp-content/uploads/2012/10/e10a13fa3a3d7f660abf9aabe9651078.jpg

Are the meta tags correct on my page?

This is the PHP code I use to post the recipe to my facebook page:

$params = array('access_token'=>get_option('weekmenu_social_fb_access_token'), 'message'=>$message_facebook, 'link'=>$link);
$url = "https://graph.facebook.com/".get_option('weekmenu_social_fb_page_id')."/feed";
$ch = curl_init();
curl_setopt_array($ch, array(
   CURLOPT_URL => $url,
   CURLOPT_POSTFIELDS => $params,
   CURLOPT_RETURNTRANSFER => true,  
   CURLOPT_SSL_VERIFYPEER => false,
   CURLOPT_VERBOSE => true
));
$result = json_decode(curl_exec($ch));

Where lies the problem?

Answer 1

Facebook caches its results the first time a page is scraped – to force that to refresh, you need to use their URL Linter.

If you put your page’s address into that tool, the correct information will be displayed the next time the link is posted to facebook.
