Unknown column 'auto_network_configuration' in 'field list'

I am trying to re-add my server through the server config page after I deleted it whilst experimenting, as any FTP logins I added were not working. I believe this was due to the server ID for the FTP user (in the ftp_user DB table) not being '1', as delcared in /etc/pure-ftpd/db/mysql.conf (the server_id for added logins was 0).
