How can I have a block show only on the /user page, but only for users with specific role? I have users with the role "authors" and a block in /user showing publications so that visitors can see the publications of every "author". The problem is that the block is showing at every user profile page even if the user has not an "author" role. How can i set this block to show only to user profile pages that have a role "author"?
On the configure block page, at the bottom in the vertical tab menu, click on the roles tab, and select which user role you want it to display for.
