Site settings
Contact form settings
Set the Google reCAPTCHA site key used by the contact page's spam check. Get a key from the reCAPTCHA admin console.
This is the public site key (not the secret key). It is saved in this browser only.
This stores the key in this browser's local storage only. To apply it for every visitor, set it in the same browser used to manage the live site, or ask your developer to hard-code it into the contact page instead.
