My site is private, and I do not want search engines to access it or bots to know the file structure.  I followed the instructions in post-41787 (harveysamui) - I disabled the User Profile Page indexing options in Dashboard > Forums > Settings > Features admin page, and I added the text below to functions.php, then deleted the cache:

function custom_wpforo_seo_options($options){
   $options['topics_sitemap'] = 0;
        return $options;
   }
add_filter('wpforo_seo_options', 'custom_wpforo_seo_options');

Neither of these worked; I still have complete access to the sitemaps.  I am running wpForo 1.7.0.  Any other options?

Thank you.
