Hey there Chip,
Been reading all the support posts about the cbnet Really Simple CAPTCHA Comments and can not seem to find the solution to my problem.
I am running WP3.9 / Really Simple Captcha 1.8 / cbnet Really Simple CAPTCHA Comments 2.1.
It works perfectly on my Contact Form 7 but nothing on the comments area.
When I add <?php cbnet_comment_captcha(); ?> in Appearance > Editor > comments.php (right after the comment entry TEXTAREA form field or anywhere else around it) everything below this php tag (including footer) disappears from the pages.
Can you please tell me what I am maybe forgetting or direct me to the correct support post on this issue?
