Plesk No FTP PermissionsThu, 16 Dec 2010
If you are using Plesk and hosting several domains you may run into a problem with FTP not giving your other FTP users sufficient privileges to modify files. I'll show you how to fix this when Plesk gives no ftp permissions. I also had this problem with Plesk not giving me FTP permissions, hence the post :)
1: Login to SSH, get inside your super user and go to your folder.
$ su $ cd /var/www/vhosts/yourdomain.com
3: Give the desired user permissions recursively (to Sub-folders too)
$ chown -R ftpuser httpdocs/
4: Login to your FTP with that user, and try to change file permissions or upload a file. If it's not working, make sure you included a trailing slash on the chown command.
For a master FTP user you can allow him permissions over many things, but I would not recommend this for security purposes. Use with caution
$ chown -R mainuser /var/www/vhosts/
