Subdomains work perfectly, but that's not what I'm interested in. In the in the past, I have done this many times with no problems. Only two explanations for this.
The plug-ins have changed drastically, I forgot how. I am on a new host and maybe it's different.
https://workflowy.com/s/D317WYObOj contains more detailed information, list the plug-ins etc.
This may be one of those problems were logging in is a great idea?
