[Plugin: Social Discussions] Nothing is shown

I don’t see anything shown in my posts or anywhere else. Using the function “laecho_wp_filter_content_widget” doesn’t work neither. Is this plugin still working for some user or it’s only used to auto-post?

I saw many questions here with no answers given at all, and I don’t want to spend time on digging up into the plugin code if there is no serious support behind it. So this question is also a check on whether the team is taking care of this plugin with care or not.
