title: Google +1 button causes JavaScript error
body: <p>We've recently started using the Google +1 button on our page, but whenever we include the Google script block this JavaScript error comes up in IE8:</p>
  
  <blockquote>
    <p>"No relay set (used as
    window.postMessage targetOrigin),
    cannot send cross-domain message"</p>
  </blockquote>
  
  <p>This is a weird one, can't find out much about it. Does anyone have any clue what it means? I've tried moving the script include to the top of the page, but it doesn't help.</p>
