title: object doesn't support this property or method btoa
body: <p>I know there is already a question on here with solutions for this but I have little understanding of javascript and I can't seem to figure out what they are saying to add in or where. The link to it is here: <a href="https://stackoverflow.com/questions/18286745/iexplorer-script438-object-doesnt-support-property-or-method-btoa">IExplorer: SCRIPT438: Object doesn&#39;t support property or method &#39;btoa&#39;</a></p>
  
  <p>Can someone explain to me what they are doing to make it work? Thanks.</p>
