This article journal have refbacks on footer (pict 1), when I see my journal There are currently no refbacks on article (pict. 2). The question is are Refbacks is automatically without setting or add something link on configuration on somewhere?
after you have enabled the refbacks plugin the system registers the links to your articles after they have been clicked. But for them to show the author needs to publish them. So the author needs to login (or you, if you have the rights, can log in as the author), then needs to go to his author’s page and then he sees all the new rebacks and can publish them (or ignore them or delete them, if he chooses to do so).
I would recommed to make several exlusions, for example for search machines.
