Small icon "Online Comments"

@cuk,

Yes if it's possible. 

You can also create a dev/staging copy of your website in some sub-domain and send admin details to info[at]gvectors.com email address.

You can use Duplicator to create that site. It's too hard to check the issue on your live website.

@cuk,

The sorting buttons (including the inline commenting) are not available for the default comments pagination type [1][2][3]... It's only active for [Load more] and other AJAX pagination types. So navigate to Dashboard > Settings > Discussions admin page, and uncheck the "Break comments into pages with…" option. 

It's described here: https://wpdiscuz.com/community/f-a-q/if-the-wpdiscuz-sorting-buttons-are-missing/

Regarding the second issue, I'll let you know a bit letter.
