Can you access your site via your host? Like: get to cpanel and see your databases in phpmyadmin? I'd be making sure the database is still there, and I'd be comparing the date/time stamps and byte sizes on the files in my /conf/ folder on my server and my computer to see if there is anything hinky going on.

Yes, I even ran the diagnostics and repair options that were available in the cpanel, and they said everything is fine.

I did install a new shopping cart on a seperate new database. That's the only thing I can think of that might affect it, but shouldn't.

How about comparing the conf/_basic_config.php from your local copy to your server version? If the file on your server went belly up then you won't be able to connect anymore is what I'm thinking.

Problem solved :

The fact that I created a new database with the same username but a different password for the shopping cart via the cpanel database setup wizard also changed the passwords for the other databases. Strange. Oh well, we live and learn.

I feel much better about re-doing work on the cart than on my b2evo sites.

Thanks EdB for trying to help. It helped me sort through the possibilities.
