Okay, guys... I managed to settle here after a lot of fighting, the flow is as follows:
1- create your facebook app with any name; 2- set it to be an app for a website and make the same public; 3- in the app’s platform configuration, select 'website'; 4- enter the tag
<meta property="fb:app_id" content="(seu app id)">
before head closure; 5- insert jdk right after head opening :
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/pt_BR/sdk.js#xfbml=1&version=v2.10&appId=(seu app id)";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
6- Enter the tag in the location you want the comment box to appear:
7- go to comment moderation settings, click settings and turn on 'comments mirroring' or 'comments mirroring', something like that. https://developers.facebook.com/tools/comments
By now the comments should be showing 'mirroring''.
Any questions you may ask me. hug.
Hugo, if you found the solution, post it as an answer below and mark it as accepted. Using the above question field will confuse your post. This site is not like forums, visit the [tour] to see how it works.
