Sniffing usernames and passwords with ettercap

[ampakine]

I'm playing around with ettercap at the moment so I can learn how to use it. I have a 2nd laptop right next to me to practice on. I can successfully pull off an arp poisoning MITM and sniff plaintext HTTP traffic (including usernames and passwords) with wireshark but for some reason nothing comes up in ettercaps text box (the place that sniffed usernames and passwords are supposed to show up). I ARP poisoned the victim comp and my router and ticked the "Sniff remote connections" box. What am I doing wrong?

EDIT: I enabled SSL dissection and tried sniffing HTTPS login info and it worked:

wait, so you were able to sniff SSL but not http traffic? No sense that makes.. probably just had some settings derped up.
