Okey ... i have resolved ...
In /script/fixmail-all; i followed => fix-qmail-assign.php => slave_get_db_pass => lib.php => dbadmin and see that password (i dont know why was different
), i have changed it and then ... /script/fixmail-all; (now) fix-qmail-assign.php works ...
but ... i dont understand why ... if KloxoMR fails to connect to the db ... doesnt give an ERROR in the script ...
