After booting, the elog was only showing logs from before July, and was missing the "For Shifters" category. It appears we were loading the incorrect config file. The running command was:

/usr/sbin/elogd -D -c /etc/elogd.cfg -s /usr/share/elog/ -d /var/lib/elog/logbooks/

while it should have been:

/usr/sbin/elogd -D -x -c /home/dsproto/online/elog/elogd.cfg -s /usr/share/elog


rc.local was set up to run the latter command, but rc.local~ had the prior version. Perhaps that was being picked up. I have deleted the rc.local~ version, and will see if elog starts correctly next time we reboot.
