What happens sometimes is the 'owner' of the file gets changed and then you are not able to make any modifications to it. You can see the 'owner' column if you turn it on in Cute FTP. Usually it will default to your username, but if it gets set to Apache or something other than the username, it may not be able to be changed via FTP. The solution would be to use the chown command, but your host may be able to assist you with this if you are not familiar with shell access.
