OK. I am making some progress but am having a permissions issue. When I do the apache config test, I get the following errror:
httpd: Could not reliably determine the server's fully qualified domain name, using [computer name].local for ServerName
I discovered this after trying to access Sites and getting told I do not have permission to do so.
My computer name is pretty complex, and I could change it. But then I worry about how to handle my long-standing Time Machine backups. Does TM use the machine name or the disk id or both?
Sorry to be such a pest. I did this a number of years ago on a different machine. I fear that my 72 year old brain is fading:-(
