PHP4 is deprecated. In order to remove it from our LiteSpeed installs, is all that is necessary to run a delete on... LSAPI App lsphp4 uds://tmp/lshttpd/lsphp4.sock ? Or is there additional modifications needed?
no need delete it.
in lsws admin console, check "Script Handler" settings.
as long as .php is associated with lsphp5, lsphp4 is not called for .php script.
