Pure-ftpd is a bit tricky to configure because do not handle the configuration like any other daemon in Linux so you will not find any /etc/pure-ftpd.conf.
According to the pure-ftpd documentation, you should start the daemon already with the options you need. The default Ubuntu installation, use the files in /etc/pure-ftpd/conf/ to set the options for the startup script of pure-ftpd so, to disable the logging, execute the following command in your shell and restart the daemon
$ echo "none" > /etc/pure-ftpd/conf/SyslogFacility
$ /etc/init.d/pure-ftpd-mysql restart

Thanks Antonio. I was looking for that.
How on God’s green earth did you find the exact upper and lower case letters to use for that switch?
I had figured out I needed to create files inside /etc/pure-ftpd/conf/ to set pure-ftpd’s switches but can’t find anything in the documentation regarding what he does and does not read or the exact case for the file.
I’ve googled myself silly and found plenty of pages on this or that option (like your page on the option I was actually looking for) but no definite list of all available file options. Any pointer?
Thanks again.
