Hot damn! I swear I read those exact directions before and followed them to the letter. Ah, well. It worked this time. Thank you both for your help.
I don’t know if it had anything to do with it but I didn’t have an FTP account on my computer the first time I tried it all. After I got my Filezilla account (more tribulations in that, as well) and did the same steps, it worked. It’s like magic at this point in my understanding. “How did it happen? Magic, I guess.”
One day it will all make sense and I will be in position to offer sage advice to the lost and flustered.
Thanks again.
