Virtual Multi server Interface error

Hi!
I have a problem, I installed two servers:
1-web, ftp, interface ....
2-mysql, email .... no interface
when I try to connected with a client account I have many errors like this:

Code:

#0 db->query(SELECT COUNT( * ) AS cnt, sys_datalog.action, sys_datalog.dbtable FROM sys_datalog, server WHERE server.server_id = sys_datalog.server_id AND sys_datalog.user = 'test' AND sys_datalog.datalog_id > server.updated GROUP BY sys_datalog.dbtable, sys_datalog.action) called at [/usr/local/ispconfig/interface/lib/classes/db_mysql.inc.php:158] #1 db->queryAllRecords(SELECT COUNT( * ) AS cnt, sys_datalog.action, sys_datalog.dbtable FROM sys_datalog, server WHERE server.server_id = sys_datalog.server_id AND sys_datalog.user = 'test' AND sys_datalog.datalog_id > server.updated GROUP BY sys_datalog.dbtable, sys_datalog.action) called at [/usr/local/ispconfig/interface/lib/classes/db_mysql.inc.php:379] #2 db->datalogStatus() called at [/usr/local/ispconfig/interface/lib/app.inc.php:217] #3 app->tpl_defaults() called at [/usr/local/ispconfig/interface/web/index.php:64]
