Forum Thread: MITMf Not Sniffing

So I've been looking at a tutorial on how to sniff a target computer using MITMf and I have run into an issue. I downloaded the framework from the repositories in the kali distro I am running. And do not have any issues running the attack, however when I run this command

"mitmf --arp --spoof --gateway <router IP> --target Target IP> -i wlan0"

But I am hit with this error immediately

" Traceback (most recent call last):
File "./mitmf.py", line 81, in <module>
settings.Config.populate(options)
File "/usr/share/mitmf/core/responder/settings.py", line 72, in populate
self.SSLOnOff = self.toBool(self.config'Responder''HTTPS')
File "/usr/lib/python2.7/dist-packages/configobj.py", line 554, in _getitem_
val = dict._getitem_(self, key)
KeyError: 'Responder'
"
And I am unsure how what I should change in the code to rectify this mistake
Thanks in advance :)
