Hello,
as @notcastey said:
Edit with Nano or emacs (you need to install it before to use it) (apt install emacs)
emacs /usr/local/lscp/conf/bind.conf
And then change the 8888 with 8090 to restore the port (CTRL+X and CTRL+C to exit):
*:8090
Then put in the console:
cd /usr/local/CyberCP/
And modify any file with 8888 port writing:
grep 888 /usr/local/CyberCP -rl |grep -v “.php\|.css\|.js\|.pem\|.html\|.png\|site-packages”|xargs -i sed -i ‘s/8888/8090/’
Then type:
sudo su -
systemctl restart lscpd
That way I solved it.
