Comments not appearing on posts


I am using your plugin on my blog and it works. However, I have a problem with the comments not appearing. For example:

This post is published on Facebook: and on Facebook it has a couple of comments and likes. It shows two comments on the WordPress side of things but I do not see the actual comments.

Also I tried ‘import comments now’ and no comments seem to be imported for my other wordpress posts.

Thank you in advance
