Failed attempt at creating SFTP and SSH Users

Hi guys .

I just followed these instructions:

https://easyengine.io/docs/chroot-sftp-easyengine/

everything was going great until I encountered these problems.

In this step :

root@example.com:~# vim /etc/ssh/sshd_config
# Find below line
Subsystem sftp /usr/lib/openssh/sftp-server
# Replace above line with following line
Subsystem sftp internal-sftp

# Add following lines at EOF
Match group www-data 
X11Forwarding no 
ChrootDirectory %h 
AllowTcpForwarding no 
ForceCommand internal-sftp

I blocked my self into ssh ....

and the second situation .

I can't upload any image in wordpress or php

Thank you
