When trying to access a specific folder, my FTP user is getting permission denied. I've tried using chown to fix it, but it won't work. The FTP user is web4_phigam. However, the files/folders are owned by "derek" and in the group "web4." The phigam user is a user in /etc/passwd and it is administrator according to ISPCONFIG's web interface. When using "chown -R web_phigam web/" the option doesn't stick to the files. How can I get the directories to be owned by the correct user?
