You got to have some basic knowledge to run Apache or LSWS. You can google it what the "http port" means. don't think you need college degree to understand it.
Back to your issue, basically, you can not have both apache and lsws listen on http port (TCP port 80) at the same time. To work around it, do either of the below:
1) Stop apache and have lsws listen on http port
If you use cpanel, go to WHM=>plugins=>LiteSpeed Web Server=>Switch to LiteSpeed. That should do it.
2) Have apache run on http port and lsws run on a different port (Offset port).
If you use cpanel, go to WHM=>plugins=>LiteSpeed Web Server=>LiteSpeed Port Offset =>Change=> 2000. Then reststart LiteSpeed.
