Plugin breaks jetpack comments and hides other widgets

Hello,
The plugin is great, but after the latest update I ran into a couple of problems.
The plugin disables the jetpack comments on my blog, and the widgets are not visible on post pages. The widgets are visible on the homepage but not on the posts.
How can I get around this since I don’t want to use another plugin.
my site: icafekenya

thanks
