Server :: Vsftpd 550 Access Denied On CentOS 5?

I've only recently encountered this problem with vsftpd when I was creating new ftp accounts. I keep on getting:

550 Access Denied.

on every action I try to do on ftp, no matter what. I've been trying to solve this myself however my attempts have been futile.

The permissions, and ownership have been checked and rechecked tens of times now, so thats not the issue. I've reinstalled the OS of my server twice now, and the problem is still persisting. Heres my config file, this isnt for anon by the way.

Code:
# Example config file /etc/vsftpd/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
