ERROR for site owner: Invalid domain for site key

I add the Site and Secret Keys to the Captcha but I'm still getting the " Invalid domain for site key" error.

The plugin is published and the "Default Captcha" is changed to "CAPTCHA - reCAPTCHA" in the site settings.
​
Any idea why?

Thanks!

the plugin you're talking about has nothing to do with Chronoforms. And it sounds like you need to set up your recaptcha settings properly

OK. Thank you. I had missed a step.
