FTP permissions problem

[rpguk]

I have some folders and files which simply won't let me upload, rewrite, rename, change permissions etc. Any action I try to perform on them simply gives me an error such as

 550 Could not change perms on /public_html/foldername: Operation not permitted 

the current permissions seem fine (755) and cpanel's file manager isn't having any luck either.

any ideas greatfully appreciated, work has halted as a result

Ask your host to sort it for you, but 755 is all you should need, anything past this is very very insecure, and shows a deeper issue with your webhosts setup.
