title: reCaptcha works locally but not on PythonAnywhere
body: <p>Locally on <a href="http://127.0.0.1:8000/" rel="nofollow">http://127.0.0.1:8000/</a> reCaptcha works as expected.
  When deployed to PythonAnywhere ("production") on the form it is supposed to work, I get only "Verify" (the label) but nothing else.</p>
  
  <p>I have used to keys from Google in db.py as:
  from gluon.tools import Recaptcha
  <code>auth.settings.captcha = Recaptcha(request,
      '6LeHlgMTAAAAAPMaNZSNaaYabmbr8amc6BzjAjsu', '6LeHlgMTAAAAAKCaa8nUQsmDPjpAAh_CIR40o7G')</code></p>
  
  <p>I have added the script from Google in layout.html
  And another script from Google at the end of the form where reCaptcha is supposed to be.</p>
  
  <p>I know that locally reCaptcha is not really checking the public/private keys, and that may explain why it works locally, but still - what am I doing incorrectly ?</p>
