captcha and comment not working

I am trying to set up a blog and I have added some sample blog posts. I tried to add a comment as a guest (not logged in). I believe I have enables guest commenting. I have also added a recaptcha site and secret keys, but it does not show up on the page, just the words Captcha image (See attached image). When I try to comment, I don't get any error, message, but the comment does not show up on the back end nor do i get an email. I assume I am missing some proper setting but I can't figure out what it is.
