problem to configure ntop on ubuntu 14.04

Hello everyone!!! I just ask for your help concerning ntopng configuration. I installed it with no problem but when I run the following command, I have this:

#sudo service redis-server restart && sudo service ntopng restart Stopping redis-server: redis-server. Starting redis-server: redis-server.

• Stopping ntopng /etc/init.d/ntopng: line 64: [: too many arguments /etc/init.d/ntopng: line 68: [: too many arguments
