forum subscription (bbpress)

[kezko]

Hello,

I want to have the “forum subscription” feature for the bbpress plugin.
Currently, subscription to a topic works fine, but the forum subscription button is not there.

I found this : https://bbpress.org/forums/topic/no-forum-subscriptions-update-to-2-5/

So I wonder if this is a child theme for bbpress that needs to be updated to have this feature. If yes, someone could he tell me how to do ?

Thank you
