Facebook Open Graph, Google+ and Twitter Card Tags with Access Token
If you want the "Facebook Open Graph, Google+ and Twitter Card Tags" WordPress plugin to be able
to clear/update the cache of your posts and pages, you'll need to create a facebook app and add
it's ID and secret to the URL.
1) Go to and create a new app (or choose and existant one, any app will do)
2) Copy the App ID and App Secret from your app dashboard
3) Add this to your (child-)theme's functions.php file and replace MY_APP_ID and MY_APP_SECRET with your app details
add_filter( 'fb_og_update_cache_url', 'my_fb_og_update_cache_url' );
function my_fb_og_update_cache_url( $url ) {
$url .= '&access_token=MY_APP_ID|MY_APP_SECRET';
return $url;

Use the snippet in your child theme functions.php file. You can omit the <?php opening tag.
