Hahahaha. I found the error.
Basically the area where you enter your ‘site key’ & ‘secret key’ doesn’t allow special/punctuation characters.
So all you need to do is delete your current google reCaptcha keys and re-create new ones until you get ones with out special characters.
Took me a few tries 😀
I’m also getting “Invalid Site Key” using reCaptcha. Any fixes?
