It's a WordPress site. I am using Contact Form 7 with reCAPTCHA V2.
When I submit the form, it fails to submit.
Looking at the reCAPTCHA management screen, it says:
We've detected that your site has a reCAPTCHA success rate of less than 50%. This may indicate a problem with your reCAPTCHA integration.
I have written this:
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<action="?" method="POST">
<div class="g-recaptcha" data-sitekey="MY KEY"></div>
<br>
I want the reCAPTCHA to succeed so the form can be submitted.
I found the cause of this problem.
Because it was a verification environment, it was the cause that the mail setting was not done.
