500 SITE not understood 500 Unkown command 500 SITE CHMOD command not understood 502 Command 'SITE' not implemented
The errors above vary from server to server. The host ftp server does not support the SITE command therefore it is not possible to send the SITE CHMOD command to set permissions on files or folders.
If your server does not support CHMOD you need to contact the host of the FTP server for further assistance. CHMOD stands for change mode: command to change file system modes of files and folders such as permissions.
