I happened to look into te syslog of my raspberry Pi feeding fr24 because of another problem but found the syslog full of error messages because of fr24feed:
Every minute, all the day there is added a line to the syslog saying:

M dd hh m sec raspberrypi/usr/sbin/ cron[****]: (*system*fr24feed_updater) WRONG FILE OWNER (/etc/cron.d/fr24feed_updater)

What is going on?

my fr24 build version is 1.0.16-7
build revision is master-d6572f3.git
