You can try setting the Session as a storage for the captcha image by following the first two steps from this help article and checking if the problem persists.
In case the captcha is still not working, could you please let me know if there is something specific in the setup of the control on your end that will allow me inspect the problem locally?
curl_setopt($ch, CURLOPT_POST, count($fields)); curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Execute post $result = curl_exec($ch); // close connection curl_close($ch); // If result failed (NULL or FALSE) if( !

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…
From a UX point-of-view, CAPTCHA is never required for a good UX.
Captcha pushes the burden of spam prevention onto the end user instead of onto the site administrator, which is bad UX. :-) Can a script that's smart enough to find your site and fill out its registration form check an e-mail inbox (or a web-based mailbox like guerrillamail.com) and open a link?
This form of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen.
Because the test is administered by a computer, in contrast to the standard Turing test that is administered by a human, a CAPTCHA is sometimes described as a reverse Turing test.
This user identification procedure has received many criticisms, especially from disabled people, but also from other people who feel that their everyday work is slowed down by distorted words that are difficult to read.
