Email link on photo comment not working


I have the following configuration: rtMedia 3.8.1:

  • Enable user comments on media files - ON
  • Use lightbox - ON inspireBook theme 1.2.16

In one of my public groups there is an album with photos. When a user comments on a photo, an email is sent out with the following link, which is broken:

Please advise. Is it a theme problem or rtMedia?

Thank you!
