Hello,
Google requires specific white-listed parameters when setting up your reCaptcha key. From the FAQ
localhost domains are not supported by default. If you wish to continue supporting them for development you can add them to the list of supported domains for your site key. Go to the admin console to update your list of supported domains. We advise to use a separate key for development and production and to not allow localhost on your production site key.
We suggest whitelisting the local IP (127.0.0.1) and the root local development URL. I.E. if your local URL is localhost
you would add localhost
. If you’ve added a local virtual host you would need to add that virtual host URL too.
Hopefully the above solves your issue. Should you have any other questions please reply back to this topic. Have a wonderful rest of your week!
