i get a cgi script which says.
# Full Server Path (NOT URL) to your "data" folder. For Security this directory # should be placed one level below your public html folder. Like place it in:
# /home/sites/www.yoursite.com/data instead of
# /home/sites/www.yoursite.com/web/data
# Also CHMOD this data folder and every file inside it to: 0777
$data_dir = "";

what's the data _dir?I think on my server it should be as follows
on my server,is it as /var/www/html/data ?
but is it right ?
