I try to add simple Like button to my Facebook Canvas app (iframe). The button (and all other XFBML elements) works in Safari, Firefox, Opera, but in Google Chrome. How can I find the problem?EDIT1:This is ERB-layout in my Rails app<html xmlns:fb='http://www.facebook.com/2008/fbml' xmlns='http://www.w3.org/1999/xhtml'>...<body>...<div id=fb-root></div><script>    window.fbAsyncInit = function() {      FB.init({        appId: '<%= @app_id %>', status: true, cookie: true, xfbml: true      });      FB.XFBML.parse();    };    (function() {      var e = document.createElement('script'); e.async = true;      e.src = document.location.protocol +        '//connect.facebook.net/en_US/all.js#appId=<%=@app_id%>&amp;amp;xfbml=1';      document.getElementById('fb-root').appendChild(e);    }());    FB.XFBML.parse();</script><fb:like></fb:like>...JS error message in Chrome inspector:Uncaught ReferenceError: FB is not defined  (anonymous function)Uncaught TypeError: Cannot call method 'appendChild' of null  window  (anonymous function)Probably similar tohttp://forum.developers.facebook.net/viewtopic.php?id=84684
Why does XFBML work everywhere but in Chrome?
javascript;google chrome;facebook application
I'm doing exaclty what you are doing. And it works. Try this snippet.<div id=fb-root></div><script src=http://connect.facebook.net/en_US/all.js></script><script>  FB.init({appId: '<%= @app_id %>', status: true, cookie: true, xfbml: true});  FB.Event.subscribe('auth.sessionChange', function(response) {    if (response.session) {      // A user has logged in, and a new cookie has been saved    } else {      // The user has logged out, and the cookie has been cleared    }  });</script>
