of comments not showing in title

I use this Plugin for Facebook

vivacityinfotech.net/wordpress/plugins/wp-facebook-comments-by-vivacity/

With this theme

https://smthemes.com/middleearth/

and this is my Blog's link

http://paranormalementquebecois.com/

If you look at every post's titles, I cannot get the # of comments to show up. It always shows up the number 0. I only need the FB comments.

What files and lines should I modify to get the # of comments to show up ?

Thanks for your help.

Hi! We show number of comments with function comments_popup_link in the file theloop.php.

This function counts only standard WordPress comments, that users leave using comments form on your website. To show number of comments from Facebook, you should contact plugin developers.
