Hello,

The app suggests friends of your friends as possible new friends (people you may know) for you. So, if you don't have any friends at all then 'People You May Know' block will be empty.

By default the block is added on Home, Dashboard and Profile pages. Did you check them there?

Feel free to contact us via PM if you need us to check the app directly on your site.
