Display a user’s group next to their avatar issue

Hi everyone, i searched for the post above and tried it, but i did not work :

  1. Here is my site : diendannangluongtaitao.com
  2. And some pic :

Thank you all!

It looks like this user already has a title of “supporter”, so I think it is a question of which group is marked as the primary group?


Dear @codinghorror It’s “admin” group

So i need to change it to a secondary group so it can display ?
