I use hcaptcha NOT recaptcha. It does everything Google's version does but is a little more ethical regarding user data so i don't want to change it.
It works pretty much the same and i noticed users were having issues with recaptcha
Users can not register or sign in. I tested it myself and couldn't either. what could be the cause?
Please leave your forum URL, so we could test it. Also, please try to explain the issue again, I didn't follow you.
