The daemon section of the config file seem to not have been updated from the last version. It should be changed from:
# DAEMON CONFIGURATION
# This provides configuration for running AppRocket replicator (station.py) in daemon mode
# (using -d command-line switch).
LOGFILE = '/var/log/approcket.log'
PIDFILE = '/var/run/approcket.pid'
GID = 103
UID = 103
to:
# DAEMON CONFIGURATION
# This provides configuration for running AppRocket replicator (station.py) in daemon mode
# (using -b command-line switch).
DAEMON_LOG = '/var/log/approcket.log'
DAEMON_PID = '/var/run/approcket.pid'
GID = 103
UID = 103
