Facebook customer Chat not showing on Joomla page

Question

I have added code from messenger configurator to my page (just after opening body tag) - but the messenger window is not showing... - the code is visible when I inspect the page - I tried it in domain/test.html file and it worked just fine. Any ideas why that might happen? Already tried most of the common suggestions I could find on SO.

<!-- Load Facebook SDK for JavaScript -->
      <div id="fb-root"></div>
      <script>
        window.fbAsyncInit = function() {
          FB.init({
            xfbml            : true,
            version          : 'v4.0'
          });
        };

        (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 = 'https://connect.facebook.net/pl_PL/sdk/xfbml.customerchat.js#xfbml=1&version=v2.12';
        fjs.parentNode.insertBefore(js, fjs);
      }(document, 'script', 'facebook-jssdk'));</script>

Answer 1

searching for the div with accurate ID made me think - as it appears I had some plugin FB to show likes, that has same ID - when i turned it off chat started working just fine.
