<li> <%= gravatar_for user, size: 52 %> <%= link_to user.name, user %> <%= if current_user.admin? && !current_user?(user) %> | <%= link_to 'delete', user, method: :delete, data: { confirm: "you sure?" } %> <%= end %> </li>
change app/views/users/_user.html.erb code following:
<li> <%= gravatar_for user, size: 52 %> <%= link_to user.name, user %> <% if current_user.admin? && !current_user?(user) %> <%= link_to 'delete', user, method: :delete, data: { confirm: "you sure?" } %> <% end %> </li>
