root@controller:~#

When I click “Admin” -” System” - “System Information” on dashboard, something went wrong: An unexpected error has occurred. Try refreshing the page. If that doesn't help, contact your local administrator

2、My location information
/etc/openstack-dashboard/local_settings.py，set DEBUG=True, debug information is:
TemplateSyntaxError at /admin/info/
u'routers' is not a registered namespace inside 'horizon:admin'
Request Method: GET

3、Solution
 /etc/openstack-dashboard/local_settings.py
OPENSTACK_NEUTRON_NETWORK = {
  'enable_router': True, --》from False to True

after service restart, the problem is fix.

4、I think this is a problem
It's too unfriendly. There is no intuitive display, I suggest to modify, thanks
