ok, Nobody from LiteSpeedtech.com for helping me.
Finally I found it and seems working now.
I would like to share it with other users.
If you have open_base protection then Directory listing will not work.
For enabling this, do these steps
My litespeed installation folder is /home/lsws.
Please change below if you have other location like /opt/lsws
mv /home/lsws/share/autoindex /usr/lib/php/
cd /home/lsws/share/
ln -s /usr/lib/php/autoindex autoindex
Goto LSWS Admin panel and enable
Auto Index
Restart webserver.
Done
Hey, I am using "ln" command for the first time
Reference
Thank you
Vivek
