Prevent Facebook from loading comments from the canonical url?

Question

I have a Facebook comments plugin loading comments for URLs on example.com (e.g. example.com/sample-post), but it is loading comments for the rel=canonical link that is specified in the page head.

Is there any way to prevent this or force Facebook to load comments from example.com/sample-post?

Answer 1

As @CBroe suggested, updating the og:url fixed this issue, while still keeping canonical intact!

In case anyone here runs into this issue when using The SEO Framework, working code was:

add_filter( 'the_seo_framework_ogurl_output', function( $url, $id ) {

  if ( is_singular() ) {
      // Change singular URL here.
      $url = get_permalink();
  } else {
      // Change term/taxonomy URL here.
  }

  return $url;
}, 10, 2 );

Thank you!
