Thank you, Jason, now...
Thanks for deleting those user/passwords. Wasn't even thinking about the open forum. (desperation can truly make you stupid!)
Anyway, I tried localhost as you suggested and got a different error message, which I consider to be serious progress!
ERROR: Your MySQL user (name_removed) needs the CREATE VIEW privilege. Please update the user permissions and try this step again.
I have a ticket in with my hosting provider to help me with this.
Thanks again for your assistance!
