I found many logs in /var/log/apache2/error.log like these:

[2017-07-14 07:00:02] selfoss.DEBUG: set cookie on localhost/selfoss/ expiring in 2592000 seconds [] []

[2017-07-14 07:00:03] selfoss.DEBUG: destroy spout object [] []
[2017-07-14 07:00:03] selfoss.DEBUG: --- [] []

selfoss is running fine.

the logger_level in config.ini is set to NONE.

Somebody any ideas where to switch off these messages?
