Hi,
I do get the recaptcha if I set the setting to "password", not if I set it to "email".
And the recaptcha plugin monitors the response.
That's done thanks to the code:
function onBeforeUserCreate(&$user, &$do){
$app = JFactory::getApplication();
if ($app->isAdmin() || (@$_REQUEST['option']=='com_updateme' && @$_REQUEST['ctrl']=='subscription' && @$_REQUEST['task']=='api')) return true;
$this->_init();
if(!$this->params->get('registration',1)){
return true;
}
$do = $this->_checkCaptcha();
}
in the recaptcha plugin php file.
