No Setting option

Have you installed the correct plugin (there are some with similar names). If you have, settings appear here: https://dl.dropboxusercontent.com/s/knyth3g85cff1os/2015-01-19%20at%2017.16%202x.png?dl=0

Yes I did. I deleted the one that was there and install directly from the plugin page

Can you show me what is in your menu instead then? (screenshot)
