[GeoNode-users] python manage.py Error

[Ariel Neri]

Hi, I´m running GeoNode 2.6 in ubuntu server 16.04. I´m getting the
following errors when running updatelayers:

geonode at geonode:~/my_geonode$ python manage.py updatelayers
Traceback (most recent call last):
  File "manage.py", line 11, in <module>

    '%r: %s' % (name, e))
ValueError: Unable to configure handler 'null': Cannot resolve
'django.utils.log.NullHandler': No module named NullHandler

I have connected geoserver w a Postgis database, and it worked fine when i
had only those layers. Then I loaded new layers via GeoNode web, and the
command stopped working.
 "Collectstatic" command is throwing the same error.
I did not change LOGGING in settings.py. and did not override in
local_settings.py
I did changes according to this
http://docs.geonode.org/en/master/tutorials/admin/customize_lookfeel/customize/setup_admin.html
.
I´m not a programmer so please, take that in account on your suggestions or
answers. Thanks!
