[Plugin: Flattr] Button not showing up

I am not a 100% sure if this is the same problem but…

The dynamic button isn’t showing up in my posts (There is a div with a link, but its display:none;)

If I set the button-type to static button everything works fine. I suspect, that the plugin’s js is not imported into the theme. But up to now I had no time to confirm this.

@corelgott: Your theme needs to include the wp_footer() method to have the javascript printed as it’s for performance reasons included at the end of the page. The included script should then look like:

<script type="text/javascript">
  (function() {
    var s = document.createElement('script'), t = document.getElementsByTagName('script')[0];
    s.type = 'text/javascript';
    s.async = true;
    s.src = 'https://api.flattr.com/js/0.6/load.js?mode=auto';
    t.parentNode.insertBefore(s, t);
  })();
</script>

Mine’s not showing up either and the script is there, however it’s only an issue with firefox it seems?
