Disable nested comments for Comments in Blog Posts or for Comments in Activity Streams? Either way, this can be done simply by changing/removing styles that indent nested comments.

@heruputra – as @Mercime said, you can easily do it with CSS, removing the indent styles so that they appear to be seperate comments to the activity.

You could also use this code – https://buddypress.trac.wordpress.org/ticket/1870#comment:2
changing the depth to 1 will remove the ‘reply’ button on comments.

Thanks as well…
