proftpd: Could not chmod files

Problem

It is not possible to chmod files from a FTP client. FTP server is ProFTPd.

Analysis

Check your /etc/proftpd.conf file. It probably contains a line section like this:

# Bar use of SITE CHMOD by default
<Limit SITE_CHMOD>
    DenyAll
</Limit>

Solution

Remove (or comment out) the above shown Limit section from /etc/proftpd.org. Restart proftpd.

# service proftpd restart
