Thank you for your reply. I am going to say that the source of my problem and all my irritation is that I was going by a knowledge base article on the site that provides my ISP (VPS) service. Unfortunately, none of the information I have learned was imparted there.
The article made it sound as though you download the install script, run it, set up Webuzo and Bob's your uncle. I now know this is nowhere close to right.
I opened a ticket with their tech support and was told, successively, "it's your fault" and "you need to covert to managed VPS so we can help you with questions like this." That would be a minimum of triple what I am paying; I can't afford that. OR they could update their knowledge base article.
This has been extremely frustrating to say the least.
