>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #199485. --> Reported by: [kingandy](https://www.drupal.org/user/97865) >>> <p>I was experiencing the <a href="http://drupal.org/node/127871">Page Not Found</a> error regarding the tracker views and their feeds (group/tracker, group/tracker/feed, group/myunread, etc). It occurred to me to try Importing the og_mytracker view using the $view array from the og_views_default_views() function in og_views.inc. This gave me the following error:</p> <blockquote><p> You don't seem to have the following requirements: node_comment_statistics</p></blockquote> <p>This appears to be because the og_mytracker view includes a comment count from the node_comment_statistics table provided by the Comment module, which we had disabled. Sure enough, after enabling the Comment module the missing views magically reappeared.</p> <p>We're currently on version 3.1 but I have had a brief skim through the code and this table still appears to be used in the og_views.inc. This dependency needs to be either noted in the og.info or accounted for in the Notifications block (don't display the feed links if the Comment module is not installed).</p>
