avatars not showing, not correct – مرجع علم و فناوری

I changed site to new domain. I exported/imported reviews. Reviews show nicely, but avatars in reviews do not show correctly.

In WP Admin in your plugin settings, when I go into editing specific review, I can easily add new url link to new avatar. But when I update review and go back to front end, the new avatar does not show (to represent new link that’s in review in WP Admin).

Any ideas on what might be preventing avatars from showing correctly, and what can be done to resolved this?
