how to enable google captcha?

Answer 1

You can enable it from the Plugins option. Q2A is providing this plugin OOTB now with name as reCaptcha. You have to create Key and Secret for the same.

To create Key and Secret :- https://www.google.com/recaptcha/admin

I've tried enabling this already. However, the captcha is not showing up in 1.8.

Ohh, i am able to use it successfully.

Can you make sure one thing ? Under Spam tab for field called as "Use captcha module:" is selected to "reCAPTCHA".

I have configured this same on my local system.

Yes. It worked! Finally! Whew! It takes two hours almost after signing up on google's capcha, enabling it on the site and then finally having it show up!
