I am having a similar issue. My registration page will not show the CAPTCHA at
www.whatsupinthesky.com
I have it forced to goto https now. Would that cause anything? I can see the backend internal and external in the setup like the picture above. Just the front end it doesnt even show up even though I have it public, published in the module management as well as the Field setup. I do use JFConnect to allow the users to logon with the social media sites.
Any suggestions would be great!
