Hm…I wonder if it’s because you have a language pack. On line 18, replace ‘blogs’ with your blogs slug and see if it works.

Still, if you’re the site admin and you’re still not seeing anything, then the problem must happen earlier. The very first thing the plugin does is test whether the logged in user is a site admin and if so just gives back the activity feed unfiltered. Have you tried with both admin and non-admin users?
