Apparently I had set up WordPress to find the subfolder rather than the intended add-on domain.
The problem with these computers is that they always do EXACTLY what we tell them.
Thanks for your guidance. It certainly pointed me in the right direction.
It is, in fact, a cpanel add-on domain. I’ll try what you suggest, but I’ll want to back it up first. The last time I messed with it I lost everything and had to start over.
Thank you for your help.
