 * I have received reports from new users that when they try to register as a new
   user on the site, after they have passed the reCaptcha photo quiz and submit 
   their form, they receive this error message: **“reCAPTCHA failed. (Unknown error.)
   Please try again”**
 * This issue seem to start appearing on version 1.8.9.
    What is the solution to
   solve this issue please? I have searched everywhere but did not find anyone who
   had a solution to this.

 * This is generally a case where you need to follow up with your host to have “
   allow_url_fopen” enabled per Jessica’s post.
 * Also, we do recommend not requiring recaptcha for paid levels (credit cards are
   good at keeping out spammers), but you would still need to enable fopen on the
   host to get recaptcha working.
 * hope this helps

 * Thanks Pete, that worked perfectly for me. I had switched hosting providers and
   the new one didn’t have allow_url_fopen on by default. Adding `allow_url_fopen
   = On` to php.ini worked for my host, and for my local site on XXAMP, I had to
   add this extension to php.ini: `extension=php_openssl.dll`

 * I have the same problem, but in my php.ini I have allow_url_fopen = On…
