550 operation not permitted using FTP

ftp

I'm using FTP to manage some files on a site I run but keep seeing this (truncated) error log:

What do I do to solve this?

Best Answer

If

Command:    SITE CHMOD 777 admincp
Response:   550 CHMOD 777 admincp: Operation not permitted

occurs then it means that you have absolutely no permissions to do that, you should resolve this problem with your hosting so that they can give your permissions; maybe that folder is has the purpose to stay?
