Blog comments and likes issue since moving from .com to .org

Hi, I recently moved a site from wordpress.com to .org, guided transfer. Since moving, comments and likes to new blog posts from subscribers seem to have disappeared. When the posts go out to subscribers via email they no longer have a like button on them and I can’t find where to reinstate it. Then, when comments are posted, they don’t seem to be appearing anywhere in the back end for moderation, they just disappear. Any help gratefully received …
