Controllers not loading, no logging either

Oh! Completely missed one part of your original post. You need to point your domain to the public directory in the CI repository. Currently, it looks like it's pointing to the main directory (with application and system as sub-directories). That's not how CI4 is designed to work for a security best practice.  Point the domain to the public folder and you should be good.

It is (and was prior)

In fact the above image's URL is http://ci4.kaosweaver.com/img.png and if you go to http://ci4.kaosweaver.com/ you see the welcome message.
