That message warning typically indicates that a large number of attempts to solve reCAPTCHA challenges have failed or that there is suspicious activity that suggests the presence of bots. I recommend using Cloudflare Turnstile or reCAPTCHA v3.
Thanks a lot for replying. So I guess it is due to the failed attempts registered during my test phase. So I guess this warning will disappear eventually.
I tried reCAPTCHA v3, but for some reason I don’t see any reCAPTCHA stuff/icon once I save the settings. Also, the reCAPTCHA (v2) is visible only within the registration form (the one that I really need for now).
I use Frosty Media Custom Login plugin and “Theme my Login” plugin which I don’t think it makes any interference.
The reCAPTCHA v3 should appear to the bottom right by default. Make sure you provide correct site and secret keys in the settings for v3 (Captcha Settings > Google reCAPTCHA Version 3).
I have tested v3 with “Frosty Media Custom Login” and it works for login form and register form.
With “Theme My Login”, it will work for register form but it won’t work for login form as our plugin checks if its the WordPress standard wp-login.php for the login form.
You may also want to try Cloudflare Turnstile which is user-friendly to quickly confirms if visitors are real without solving any visual puzzle. Here, also make sure to provide correct site and secret keys for Turnstile. The instructions on how to get them are in the settings (Captcha Settings > Cloudflare Turnstile).
Ok I understood why I couldn’t make v3 working! 🙂
It was due to the fact that I forgot I created v2 only reCAPTCHA site on Google.
Thanks a lot!
