thank for your help, till
but I'm trying install fedora and ispconfig again.. (before you posted)
I have been run "/root/ispconfig/php/php /root/ispconfig/scripts/shell/webalizer.php" command.
there is no error.
in first time, I saw that command create folder "stats" for each website.
After that, when I run that command , it doesn't appear anything.
It use only 1 second to run the command.
