I had free version working on a web site..I upgraded to Pro 2-5 License and loaded on to the original site (with Free version) plus loaded on to an additional web site.
Original web site and additional web site not showing reCaptcha image.
Have Have “activated” pro and de-activated(removed) free version.
License number correctly inserted and saved on both sites.
Version V2 “I’m not a robot” selected.
Original site still has Site Key and Secret Key from free version
New site is unable to obtain Site Key or Secret Key –
when attempting to get them from “Google” it indicates I only have 1 site (original site)
I have gone to -settings-advanced noCaptcher & invisible captcha- and confirmed license key installed and activated.
Please go to https://www.google.com/recaptcha/admin and create new keys for new site (or you can add your new domain in existing keys also, in that case go to this url and click settings and add your new domain in domain list).
Let me know.
If still not working please include your website url in next reply.
