After backing up a database on a WP version 1.5 installation, I thought I'd be extra sure I got it by using WP-DB-Backup. It wasn't compatible with v. 1.5 and presented a message saying it remained deactivated as a result. I must have clicked on it again before uninstalling it. End result: I've now lost the connection to by DB. I now get an error saying DB connection cannot be established. I have FTP access to the DB and a successful backup. Something is not referencing the DB correctly. Thoughts?
