Troubleshooting: Recaptcha Error Message
When I am trying to register when I click on "I'm not a robot" it says problem with recaptcha, check your internet.
This could happen for a few reasons:
Are you using a recent browser version?
Are there any plugins or proxy configurations active which might interfere with google's recaptcha service?
Are you using a VPN or proxy which blocks google recaptcha?
One work around to the problem would be to sign up on another computer, or a phone. Once the account is created, the captcha won't be needed again (unless a password is forgotten).
