yes, thank you.

Unfortunately since the last update 5.3.5  answers to comments aren't possible anymore. I'm using the Stockholm theme.

Please navigate to Dashboard > Settings > Discussion admin page and make sure the " Enable threaded (nested) comments (X) levels deep" is enabled.

I can not find a function, that the rating stars will be displayed on the blog-overview-page. Is there a possibility to have that?

Please note: post_id the id of the current Post, and the post_id is deferent in each post.
