问题
I'm updating the like facebook button in my website I just followed the instructions in the facebook developer page, I'm getting the following error:
Uncaught Error: No version specified that's located in the line 82 of the facebook SDK (sdk.js)
the code is the following:
<div class="fb-like" data-href="https://www.facebook.com/fan-page-x" data-layout="button" data-action="like" data-show-faces="true" data-share="true"></div>
<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/sdk.js#xfbml=1&appId=xxxx&version=v2.0";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
The like button appears on the page but I get the error in the console.

make sure you don't have another FB JS SDK initialization code in your page.
