python 3.x - django-nocaptcha-recaptcha always shows additional verification box -

i installed django-nocaptcha-recaptcha , integrated form:

from nocaptcha_recaptcha.fields import norecaptchafield  class clientform(forms.modelform):     captcha = norecaptchafield() 

it shows fine on form, whenever click on additional dialog pops asking enter text , verify. happens every time. tested computer on network , still asks additional verification after clicking box.

this looks like: additional verification dialog box

here's how i'm handling form:

@xframe_options_exempt def registration(request):                if request.method == 'post':                 clientform = clientform(request.post)      # check whether it's valid:     if clientform.is_valid():         new_client = clientform.save() ... 

what doing wrong? problem django-nocaptcha-recaptcha? should use else?

p.s. i'm using django 1.7.1 python 3.4

restart server , don't forget clear browser's cache. hope helps.
