Answer 1

You need to tell the function "recaptcha_get_html()" that you want to use https. Replace recaptcha_get_html($publickey) with

echo recaptcha_get_html($publickey,null,1);

Answer 2

Delete "http:" from script source url.

Change it:

from:

<script type="text/javascript" src="http://www.google.com/recaptcha/api.js?render=*YourPublicKey*"></script>

to:

<script type="text/javascript" src="//www.google.com/recaptcha/api.js?render=*YourPublicKey*"></script>

Answer 3

I got the same error an tried a couple of suggestions, but nothing realy worked.

So I logged my network traffic and analyzed it. What it shows is that mid connection the servers changed from ipv4 to ipv6 and I remembered reading somewhere that recaptcha has a problem working on ipv6.

So I changed @fsockopen($host, [...] to @fsockopen(gethostbyname($host), [...] and recaptcha worked again.

Answer 4

I got the same error an tried all suggestions but nothing work for me.

then i did analyzed the issue and then i got SSL certificate issue

this certificate is only valid for the following names: www.google.com (Error code: ssl_error_bad_cert_domain)

so i changed

echo recaptcha_get_html($publickey,,true);

@fsockopen($host, [...] to @fsockopen(gethostbyname($host), [...]

along with

define("RECAPTCHA_API_SECURE_SERVER", "https://api-secure.recaptcha.net");

to

define("RECAPTCHA_API_SECURE_SERVER", "https://www.google.com/recaptcha/api");

in recaptchalib.php and recaptcha worked again.

Answer 5

edit recaptchalib.php like this:

find this line - function recaptcha_get_html ($pubkey, $error = null, $use_ssl = false)

change it to - function recaptcha_get_html ($pubkey, $error = null, $use_ssl = true)

argument $use_ssl is changed from false to true... rest will be taken care of by the script..

Answer 6

You need to change all http:// urls to https:// in "recaptchalib.php" file, after that this will work.
