title: CasperJS screenshots returning blank
body: <p>I have a CasperJS script I am trying to run and take screenshots, but it seems to only ever open 'about:blank' when run.</p>
  
  <p>Below is a link to the script I am trying to use if anyone can tell me where I am going wrong, </p>
  
  <p>thanks.</p>
