Millions of CAPTCHAs are solved by people every day.

re CAPTCHA makes positive use of this human effort by channeling the time spent solving CAPTCHAs into digitizing text, annotating images, and building machine learning datasets.

It does this while letting your valid users pass through with ease. Every time our CAPTCHAs are solved, that human effort helps digitize text, annotate images, and build machine learning datasets.

This in turn helps preserve books, improve maps, and solve hard AI problems.

The new re CAPTCHA model is called as “No CAPTCHA re CAPTCHA”. To integrate the new re CAPTCHA in your website forms first register your site and retrieve re CAPTCHA client and secret keys.

3.8.1 Chronoforms 5.0.16 A client reported that the Captcha on her forms is no longer working. With No Captcha, the form submitter receives an error message, form reloads with entered data, but does not email. Might be worth checking the No Captcha keys one more time???

This old re CAPTCHA model was not user friendly and had become less secure as new algorithms were developed to break it.

Therefore Google came out with a new re CAPTCHA model.

Today I tested captcha on recent versions of Expression Engine and Freeform and did not see any errors.

I think you have some problems with the server, particularly with CURL since he can not get a response from the Google API…

Google recently launched a new way to prevent bots sending form requests.
