'Facebook like code' error - solution for websites

Error parsing XML, line 658, column 62: The reference to entity "appId" must end with the ';' delimiter.

A error which occurs while adding facebook like to a blog states

Error parsing XML, line 658, column 62: The reference to entity "appId" must end with the ';' delimiter.

It can be solved by clicking on  JavaScript SDK. and copying the javascript to code of your webpage
that is

<div id="fb-root"></div>
<script>
  window.fbAsyncInit = function() {
    FB.init({
      appId      : 'YOUR_APP_ID', // App ID
      channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File
      status     : true, // check login status
      cookie     : true, // enable cookies to allow the server to access the session
      xfbml      : true  // parse XFBML
    });

    // Additional initialization code here
  };

  // Load the SDK Asynchronously
  (function(d){
     var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
     if (d.getElementById(id)) {return;}
     js = d.createElement('script'); js.id = id; js.async = true;
     js.src = "//connect.facebook.net/en_US/all.js";
     ref.parentNode.insertBefore(js, ref);
   }(document));
</script>

Change your ID, your website name.

• Now login to http://developers.facebook.com/docs/reference/plugins/like/
•  Now copy the second code and paste it on your site, where you want the link box to appear.

example: <div class="fb-like" data-send="true" data-width="450" data-show-faces="true"></div>

 'This is an example it will not work properly in your site as there is no URL address. Copy code form the link.

• same goes for the comment button.
