Namespace_Default: added a workaround for an inconsistency in SQL. Basically, if you join the same table multiple times under multiple aliases, COUNT() always uses the first instance. Was affecting the comment counter in the "discussion" button.

              It's possible that your configuration file has become corrupted and no longer sets information that Enano needs to connect
              to the database. You should have a look at your config.php by downloading it with FTP or viewing it over SSH.
              If the file appears to have been tampered with, please <a href="http://forum.enanocms.org/">contact the Enano team</a>
              for support immediately.</p>
