Cannot download emonhub logs

See this thread (specifically the last line of the last post):

EmonHub log systemd

Most of the changes are in this commit passthru("journalctl -u emonhub -n 30 --no-pager"); We just needed to add the www-data users to the systemd-journal group to allow it to read, this has been added to emonPi update and the emonhub config module readme sudo usermod -a -G systemd-journal www-data We still need to fix the log download button.
