In my site, I have buddypress installed. In activity page, It allows to comment for all thing except the blog posts. I am allowing user to create blog post. Also blog post coming on activity page, But there is no option to comment for that blog post. I checked settings and all, Tried using twenty twelve theme, Also disabled all plugin except the buddypress. But nothing helped. What should i do? My site link :https://twolyn.com/
