Ubuntu - SFTP files permission denied

Hi guys, all was working fine for years but know i´m getting "permission denied" when deleting, uploading, setting permissions, etc. in FTP client. Only on "Home" i´m able to modify files.

I use PORT 103, specified in "/etc/ssh/sshd_config".

FTP port is set to 103.

I can navigate through files and directories, but can´t edit them, only on the "home" directory.

I don´t know if this is a clue, but the command "ssh -v localhost" shows:

OpenSSH_5.9p1 Debian-5ubuntu1.4, OpenSSL 1.0.1 14 Mar 2012
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 19: Applying options for *
debug1: Connecting to localhost [127.0.0.1] port 22.
debug1: connect to address 127.0.0.1 port 22: Connection refused
ssh: connect to host localhost port 22: Connection refused

Any help?

Thanks
