Do I need to update the page comment form myself? I do not see my captcha.

In _config.php I have:

RecaptchaField::$public_api_key = 'xxxxxxxxxxxxx';
RecaptchaField::$private_api_key = 'xxxxxxxxxxxxx';
SpamProtectorManager::set_spam_protector('RecaptchaProtector');

I have modules installed: comments, SpamProtectionModule, and recaptcha

No captcha showing on page comments. Do I need to add the captcha myself, extend page comments or something and update the form like so;

$protector = SpamProtectorManager::update_form($form);

?

Thanks

You need to apply the optional extension CommentSpamProtection (https://github.com/silverstripe/silverstripe-spamprotection/blob/master/code/extensions/CommentSpamProtection.php).

Oh...totally missed that. Thanks! Will to the rescue again, much appreciated :0)

Sorry for the dumb question - but how does one apply that extension?

http://doc.silverstripe.org/framework/en/reference/dataextension#adding-a-extension-to-a-built-in-class

In case if anyone couldn't figure out how or what to add as the extension, add the code snippet below in mysite/_config.php, assuming that SpamProtectorManager and RecaptchaField configuration is already in place.

Object::add_extension('CommentingController', 'CommentSpamProtection');

with help from Pyromanik

Cheers.
