Facebook like and comment box: like count is increasing automatically
===

I am including Facebook 'like button' and 'comment box' on every page of my website. Website is in testing phase. 

**Problem 1:** When I comment on any page, it is not being displayed when I logout of facebook and refresh the same page. As soon as login again into Facebook, my comments are visible to me. That means other people can't see my comments.

**Problem 2:** Along with the above problem, when I comment on a page, it automatically increases the 'like button' count by 1. 

Is anyone able to identify the problem here? Please help. 

Note: I have included the following code just after opening the <body> tag (as per FB Javascript SDK)

    <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/en_US/all.js#xfbml=1";
      fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));</script>
