add snapwidget (instagram widget)

[LEE Fanny]

I would like to add snapwidget (instagram widget) to my homepage.
I tried to create a new HTML block and I added the snapwidget code there:

<!-- SnapWidget -->
<script src="http://snapwidget.com/js/snapwidget.js"></script>
<iframe src="http://snapwidget.com/in/?u=bHVuYXB5eGlzfGlufDEyNXw0fDJ8fG5vfDJ8bm9uZXxvblN0YXJ0fG5vfHllcw==&ve=091115" title="Instagram Widget" class="snapwidget-widget" allowTransparency="true" frameborder="0" scrolling="no" style="border:none; overflow:hidden; width:100%;"></iframe>


But it doesn't work.
I checked "yes" for "Allow iframes on HTML fields" in preferences but still...

I don't get any error but instead of the widget I get this text "rnrnrnrn"

Someone suggested to put the code inside {literal}{/literal} but it didn't work..
Any idea?
