Clickable Social Icon Links on Profile

There’s an incompatibility with the follow plugin: this TC works fine when I’m logged in, but when I access the site as an anonymous user, user cards and the user profile page are broken.

Update: this is not related to the social icon links TC. I’ll report it on the Follow plugin topic.

In /logs I see:

NoMethodError (undefined method id' for nil:NilClass) /var/www/discourse/plugins/discourse-follow/plugin.rb:74:in block (2 levels) in activate!’
