Problems testing ReCaptcha 2.0

Hi all!I am new to this forum and also new to this topic.I was thinking about using ReCaptcha on our Website and I downloaded the example code.I took the site-key from some site that is using ReCaptcha, because I first wanted to evaluate before going through lengthy registration processes.Maybe this is the cause of my problems already?The problem I am having is:When I open the HTML-file with the example code from Google, the widget is displayed, I see "no a robot" and the checkbox.If I click on the checkbox, the circle is "moving", but there never comes the green "check". No input window is opening with an additional request to enter something.I do not understand what I am doing wrong, I am using the official example code and I expected this to be working?!?Maybe somebody had similar experiences and was able to sort it out?Many thanks in advance!Georg -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
