Changing Apache and PHP versions on WHM


So, apparently I’m stuck with WHM & CPanel for a time being, so let’s make a full use of it. On my previous post I mentioned that I was required to transfer a CodeIgniter-based website to a new box. The original VPS host was built around 2013 and it uses CentOS 5.x, Apache 2.2 and…

So a couple of days a go, I foolishly attempted a “apt-get dist-upgrade” on my 14.04.3 install.
