Of course im still supporting it.. Sry, I just have been away for a month, i will try to help you as soon as possible.

@Angelus1753 :
Yes it is possible and allready implemented in the next big release (hope it doesn't much time for me anymore to finish it).

Until then:
Replace

$msgs= $DB_site->query("SELECT
  privatemessage.*,
  IF(ISNULL(touser.username),'[Deleted User]',touser.username) AS tousername,
  IF(ISNULL(fromuser.username),'[Deleted User]',fromuser.username) AS fromusername
  FROM privatemessage
  LEFT JOIN user AS touser ON (touser.userid=privatemessage.touserid)
  LEFT JOIN user AS fromuser ON (fromuser.userid=privatemessage.fromuserid)
  WHERE $cond ORDER BY folderid");

with

$msgs= $DB_site->query("SELECT
  privatemessage.*,
  IF(ISNULL(touser.username),'[Deleted User]',touser.username) AS tousername,
  IF(ISNULL(fromuser.username),'[Deleted User]',fromuser.username) AS fromusername
  FROM privatemessage
  LEFT JOIN user AS touser ON (touser.userid=privatemessage.touserid)
  LEFT JOIN user AS fromuser ON (fromuser.userid=privatemessage.fromuserid)
  WHERE $cond ORDER BY folderid,dateline ");
