I use the Advanced no Captcha & invisble Captcha Pro Plugin on my website, but didn’t work 100% correctly.
I installed the plugin, activated the license, create the google recaptcha keys etc…., after that I created a contact form 7 and added your code “[anr_nocaptcha g-recaptcha-response]”, now my problem, if I’m logged in as WordPress Administrator then the Captcha on my website is visible and it works, if logged out, and go back to the website and open the contact form, the Captcha is not visible. What did I wrong?
It seems footer script is not loaded in your website. Can you deactivate all plugins except this one and CF7 and activate one of default theme (tweenty*) then test? Then activate one by one and test. Let me know when you get conflict so that we can try to fix the conflict.
