when you google search "cwp installation"...
it leads to the main instructions bypassing where you should install the minimal versions of centos 6 and 7.
this conflicts with the cwp installation , crashing httpd and or portions of the php controller.
Or at least thats all i can figure out is the reason for a month of trying to set up cent os and in the end i set up the php version i know my scripts require and just a few apache mods and voila what once said "depricated" works fine...
in conclusion a lot of the problems here is simply improper linking to main instructions (skiping page 1 and 2) from search engines themselves.
Solution is to put all 3 steps on the final instruction page.
