I'm using v2 recaptcha and it seems to be working fine for registration but when using the Contact Us form it always fails saying "did not pass security check". I have confirmed my keys are good and confirmed that I can register fine with recaptcha, but cannot use the contact us form.

You have cleantalk poping up there when I test this, and looks like it may be related. Please disable all 3rd party items, including theme, and test this again

Thanks Marc, I just disabled it and it does appear to work. I checked the logs with it enabled and didn't see anything in the logs. I will reach out to clean talk.

Thought that may be the case. Glad to see you know whats causing it now, even if you havent got a full resolution as of yet
