Error 403 when active Litespeed

Hello
when switch webserver to Litespeed my website will be down, it seems lsphp not build and configure, and PHP not work.
I try to add php from LiteSpeed console, Script Handler but when I add php5.6 There are no items for Handler Name to choose from the list.
I build PHP from Litespeed Consol but the problem not solved.  What can I do to get the PHP to build with litespeed?

all php version in cwp need to be rebuilt with LiteSpeed flag
