Irgendwo und irgendwann gab es mal einen Thread darüber das nur die Klamm ID´s und nicht die Nicknamen in der Refübersicht angezeigt werden.
Hier die Lösung einfach die refuebersicht.php in content/konto/ hiermit ersetzen:

Code:
<? userstatus(); 

function nickname($userid) {
global $db_prefix;
$user = mysql_fetch_array(db_query("SELECT nickname FROM ".$db_prefix."_userdaten WHERE uid 

= ".$userid." LIMIT 1"));
$nickname = $user['nickname'];
return $nickname;
}  


$ebene_1 = false;
$ebene_2 = false;
$ebene_3 = false;

$ebene1 = db_query("SELECT * FROM ".$db_prefix."_werberdaten WHERE werber=".$_SESSION['uid']." ORDER BY uid ASC");
if (mysql_num_rows($ebene1)){
   while ($user1 = mysql_fetch_assoc($ebene1)){
   $ebene_1 = true;
   $count++;
   if ($count % 2 == 0){$row = 0;}else{$row = 1;}

    if ($user1['aktivzeit'] >= (time()-(86400*7))) $refstatus = '<img src="./images/gruen.gif" width="15" height="15" border="0" alt="'.date("d.m.y - H:i",$user1['aktivzeit']).'">';
    if ($user1['aktivzeit'] <= (time()-(86400*7))) $refstatus = '<img src="./images/gelb.gif" width="15" height="15" border="0" alt="'.date("d.m.y - H:i",$user1['aktivzeit']).'">';
    if ($user1['aktivzeit'] <= (time()-(86400*30))) $refstatus = '<img src="./images/rot.gif" width="15" height="15" border="0" alt="'.date("d.m.y - H:i",$user1['aktivzeit']).'">';

    $anz .= '
    <tr class="tr_row'.$row.'">
        <td align="center"><a href="?content=/nickpage&amp;uid='.$user1['uid'].'">'.nickname($user1['uid']).'</a></td>
        <td align="center">'.number_format($user1['umsatz']/100*$pageconfig['re1'],2,",",".").'</td>
        <td align="center">'.number_format($user1['gesamt'],2,",",".").'</td>
        <td align="center">'.$user1['refback'].'%</td>
        <td align="center"><a href="?content=/konto/refdetails&amp;ruid='.$user1['uid'].'" target="_self">'.$refstatus.'</a></td>
    </tr>
    ';
      $ebene2 = db_query("SELECT * FROM ".$db_prefix."_werberdaten WHERE werber=".$user1['uid']." ORDER BY uid ASC");
      while ($user2 = mysql_fetch_assoc($ebene2)){
      $ebene_2 = true;
      $count++;
      if ($count % 2 == 0){$row = 0;}else{$row = 1;}

      if ($user2['aktivzeit'] >= (time()-(86400*7))) $refstatus = '<img src="./images/gruen.gif" width="15" height="15" border="0" alt="'.date("d.m.y - H:i",$user2['aktivzeit']).'">';
