Cannot Add SDK Javascript Into Blogger [Add Facebook Like Button]

Facebook [screenshot: arief-jr.blogspot.com]

This post will shared about "Error parsing XML : The reference to entity “version” must end with the ';' delimiter". Since 5 hours ago, i'll trying to put facebook like button or box into my blog, then what happen? on my blog show notification message error parsing xml.

And i try to add this code like this;

<div id="fb-root"></div>
<script>
/* <![CDATA[ */
    (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/sdk.js#xfbml=1&version=v2.5";
        fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));
/* ]]> */
</script>

note: for fixing error parsing xml, add this code which i block with red colour.

And see again your blog,

If you want add facebook like box, you must copy paste the above code and put into tag </body> and also put this script:

<div class="fb-like" data-href="https://facebook.com/ALittleNotes/" data-layout="standard" data-action="like" data-show-faces="false" data-share="true"></div>

note: For script which i coloured with blue, change your url facebook.

And now my facebook like button has showing under my blog post.

Thanks, Have fun!
