I have 2 version of my site. They are m.example.com and example.com. So I added facebook comment plugin to both of them, but if user writes comment one of them, this comment will not seen in another.
I write some comments on example.com. So I want to see these comments also in m.example.com. What can I do ?
It´s a different URL. Try using example.com in the data-href parameter even on the mobile version:
