Recognize Recaptcha2 not working anymore

[zenewbie]

Why isn't the "Recognize Recaptcha2" cube (in tab) not working any more? I didn't change anything, and it worked flawlessly before.
I am on ZP 7.8.15.0 and tried with capmonster cloud and 2captcha on google login, but I get the error: "sitekey not found". Like I said, it worked before, and I have capmonster-credits of course.

I believe this is the issue on a particular website.
Please specify the site where recaptcha is not working anymore. Probably it has been updated there.

It's during google login.
