Hi,
Can someone help me with reCAPTCHA?
It doesynt work for me :( Only work on base captcha but reCAPTCHA is not working. Schould I do something more than configure config.inc.local.php file? I even don't seen reCAPTCHA button on website. Just get error that i cannot send change password email because of "Invalid token".

I have 1.7.2 version.
