og table & field_data_group_audience table doesn't exist http://drupal.org/node/1456356#comment-5653016

fixed by modifying code in below function

 function get_content_subdomain($nid) {
    static $subdomains;
    if (!isset($subdomains[$nid])) {
    /*  $sid = db_query("
        SELECT og.etid as nid
        FROM {field_data_group_audience} a
          INNER JOIN {node} n ON a.entity_id = n.nid
          INNER JOIN {og} og on a.group_audience_gid = og.gid
        WHERE n.nid = :nid AND n.type NOT IN (:types)",
        array(':nid' => $nid, ':types' => _subdomain_filtered_content_types()))
      ->fetchField(); */
$sid = db_query("SELECT gid from og_membership where field_name = 'og_group_ref' AND etid = :nid LIMIT 1",
        array(':nid' => $nid))->fetchField();
$subdomains[$nid] = subdomain_get_subdomain($sid);
    }
    return $subdomains[$nid];
  }
