Could you please take a look on the configuration, I think is everything OK but I can't make it work
We do not provide install reviews on demand. Please do not push credentials on us that we did not request. I understand things can be complicated sometimes to configure, but we're a small team of 3. We do not have time to help with everyones configuration. Install review is a last resort and only done if we suspect a possible bug.
With the above said it's not working because you've set "Moderators View Access Level" to "Public" within CB > Configuration > Moderation making everyone a CB Moderator. CB Moderators are exempt from captcha and is why it doesn't display. I've fixed this to a new view access level called CB Moderators that specifically includes only Super Users. Your captcha works fine now.
Will review adding a warning to CB regarding this as this seams to happen often.
