Dashboard/Forums/Settings/Forum Access - check "can like" for each access mask you want it enabled for.

Hi @superfly,

Yes, VereK is right. The Like button is only available for Usergroups who have “Can like” permissions in granted Forum Access (by default all except guests).

More info here:

The location of the like button can differ depending on the layouts you're using.

Also please note the users cannot like their own posts.
