The orange error border indicates reCAPTCHA v3 is not working correctly on your site.
You may see this error if you’ve:
- previously used reCAPTCHA v2 with CF7
- updated to CF7 5.1.1 or newer and
- not changed your previous reCAPTCHA v2 keys to reCAPTCHA (v3) keys at Contact > Integration.
Tried switch recaptcha to v3 but error still the same.
Your reCAPTCHA (v3) is possibly not done correctly.
If you are sure you’ve registered correctly for reCAPTCHA v3 (by following the instructions at reCAPTCHA (v3)) & it’s working, you should now see the reCAPTCHA Privacy badge displayed at the bottom of every page on your site (not just the pages where you’ve got CF7 forms).

If the reCAPTCHA badge is not showing, this shows that reCAPTCHA v3 is not working on your site.
Yes it looks like reCaptcha is not working. But I did not find any way fix it. No option to disable reCaptcha form CF. No effect after I replaced recaptach from v2 to v3.
What is the proper solutiong to solve it?
Finally solved using plugin Contact Form 7 – reCaptcha v2. reCaptcha v3 was not working even after I removed tag “reCaptcha” all messages became marked as spam.
