i just try to update host "Enable CAPTCHA/reCAPTCHA for Register" settings on latest 220.127.116.11 version and doesn't matter what i change, it is still used. And if user has an registration error, on second try the captcha image is no longer displayed.
i set it in the yaf_registy table in database the value of enablecaptchaforregister also to "FALSE" but no difference, it is still displayed and used even iis reset, etc.
On Host configuration, if i try to change it to "disabled" , i got
Null object cannot be converted to a value type.
