I just ran a git pull on /opt/minepeon/ and /opt/minepeon/http/ and now nothing on the settings page appears to be saving. Which file do I edit via ssh to force these settings?
Your brave

. Past these three lines into ssh as minepeon;-
touch /opt/minepeon/etc/minepeon.conf
chmod 440 /opt/minepeon/etc/minepeon.conf
chown minepeon.http /opt/minepeon/etc/minepeon.conf
That should fix it, if it doesn't get back to me.
