Thanks for your reply.
I got tired of proftpd trying to install it so many time and it didn't work, so
i installed vsftpd instead, and i follow the setup instructions to make it secure
with mysql, now i created a /home/vsftpd/user like the instructions said and was able to upload files in ispconfig , my question is :
when i upload a new index ,it didn't show because ispconfig set the directory
different , where am i suppose to put my sites files on the sever in which
directory? if i put it like what ispconfig.conf said /var/www/web1/web
i can't upload it because vsftpd use /home/vsftpd/username/site ?
how can i slove this problem ?
Thanks again very much
