I have installed contacts form in magento captcha that is google reCAPTCHA as habilito PageSpeed reCAPTCHA box out of place.
I could say that exclucion put on this list js code to avoid the run with PageSpeed that have put more and does not work.
This is the code reCAPTCHA comes out when this PageSpeed disabled:
<script type="text/javascript" src="http://www.google.com/recaptcha/api/challenge?hl=es&amp;k=6LfesvgSAAAAAID7rTArBq5KJ7VDI2211N8XUCcX"></script>
