How to Add CAPTCHA 4WP to Login Page

Hi,

I've added and set up the CAPTCHA 4P plugin to put the 'I'm Not a Robot' security check box on a custom login page.

Our login page and form are created using 'Theme my Login' and is found >>> HERE

My challenge is not being able to get the captcha to appear below the form on the login page.

I've followed install instructions at WP Beginner >>> HERE <<< but I haven't found these helpful for this situation.

Any ideas?

Thanks!

John
