I already installed django-recaptcha and included captcha in the installed applications. I use the private key and public key from this page: https://github.com/praekelt/django-recaptcha .
I have included instructions captcha = ReCaptchaField(). When I clicked on the page, it looks like this:
Captcha: Input error: k: Invalid site key format
I don’t know where the error is. It is necessary to be guided.
html looks like this:

Here is what I typed:
RECAPTCHA_PRIVATE_KEY = '98dfg6df7g56df6gdfgdfg65JHJH656565GFGFGs'
RECAPTCHA_PUBLIC_KEY = '76wtgdfsjhsydt7r5FFGFhgsdfytd656sad75fgh'
RECAPTCHA_USE_SSL = True
