Can you please give me a screenshot of your license page and error message?

You need to get site key and secret key from google. Please see https://www.shamimsplugins.com/docs/advanced-nocaptcha-recaptcha/getting-started-advanced-nocaptcha-recaptcha/how-to-get-google-recaptcha-keys/

Let me know.

If you need refund don’t worry about it. I will full refund you.

Your refund is processed.

We provide license to provide update and support.

But reCaptcha is a service of google. Every website needs to have keys from google to get that service. Our settings page screenshot is attached. You can see we provide instructions in multiple places how to get those keys.

You can suggest me how we can be more explicit with that instruction so that i can provide better instructions for all users.
