I made it a wiki. You are welcome to update the OP to better detail everything. Since you have expertise here, I do hope that you’ll watch this topic so that you can help others who want to follow in your path.
The fact remains that no one who is a regular contributor here uses Cloud Panel, and the person who created the guide isn’t participating in supporting it. Supporting just the standard install, where there is very little that can go wrong, is fairly time consuming.
