interex, thanks for the respons
i think i make mistake when change permissions.
first, dolphin tell to change permissions for back up, change, etc to 777. ok, next.
than, dolphin tell to change periodic/cmd.php and 3 other files. change to 777.
paths, database, configuration, and cronjobs, ok.
theres is permission reversal. i change periodic and inc to 755. another 4 file also change to 755.
the result is ...
