php program

Dear staff,
the php program that shows on my website the number and the usernames that 
are on my irc channel is not working.
If I use it with the chan #Todi it's all right, but if I use it with the 
chan #UmbriaVillage it's not working, it shows me something like this:

In the chat-room there is 1 users: No auth,

It tell's me "No auth" instead of username
I am sure that the password of the chan is right


The code used is the following:

 <?php
    if ( $listfile = 
fopen("http://scripts.blitzed.org/chanuserlist?channel=%23UmbriaVillage&pass=password", 
"r") ) {
      $users = "";
      $fullfile = "";
      $count = 0;
      while ($nickname = fgets($listfile)) {
         $users .=  trim($nickname) . ", ";
         $fullfile .= $nickname;
         $count++;
      }

    } else {
    $myuserlist = $lang['IRC_memberlist_offline'];
    $nickname = "";
    $listfile = "";
    $count = 0;
    $users = "";
    $thingydingy = 0;
    }


if ( $thingydingy == 1 ) {
    // Remove , from end
    $users = ereg_replace(', $', "", $users);
    $myuserlist = $lang['IRC_memberlist']." <b>$count</b><br />\n$users";
    $myuserlist;
}
echo "Nella chat-room ci sono <b>" . $count . "</b> utenti<br />";
echo $users;
?>


Please let me know

Kind Regards
Martin Sarsini
