Recaptcha works one one form but error on another

Hi
Recaptcha works fine on one form, but with exact same specs (site and secret keys) on another form get error "you didn't pass the recaptacha verification".
Any ideas?
Thanks

In the form that generates the error messg, the form does submit properly - but shows error messg.
Seems it's submitting twice, passing the first and failing the second.
The form has three fields, not linked to database, no validation settings.

Any help on this one, thanks.
The form submits successfully but displays the error messg.

Just from looking at your debug, it's submitting the recaptcha check twice. Make sure you have only one action.

Yes it does look like it but 1 action only. Same setup as another form that does not return error messg.

OK well that's a bit odd then, and you DEFINITELY deactivated the "check security fields" option in the first tab?
​
Also just putting a debugger in there won't stop the form's events, it will still send the email. You need an event loader.

OK, so that's my error. I had check security fields enabled. Suppose that was responsible for the double submission.
What is the purpose of that action?

To automatically check security fields instead of doing it through an action. The action let's you customise what happens if something isn't valid or lets you make more complicated conditional validation

I thought Captcha, Honeypot etc is used to catch bot submissions. How do u do that with check security fields ?

It does it automatically, and redirects back to load automatically

OK, so I still have to get Captcha keys but don't have to set any action?

That's right but I prefer doing it manually and controlling what happens

Got it. Thanks for the help Healyhatman.
