Now it works! Thank you very much!
Have a nice day!

Try using Threaded layout, each layout has its design so the Primary Usergroup would be displayed in different places ass well.

thanks. As you see here, I made the changes, but I can't see the usergroups somewhere on the post site. The user profile can be seen here. The user has the usergroup "System" but its not shown on the post page next to the name as its shown here next to your name.

Navigate to wpForo > Settings > Member Profile, and check your Usergroup in Display Member Primary Usergroup

I mean this Admin tag.

Navigate to Dashboard > wpForo > Settings > Member Rating, and check those settings, there are all settings you need for wpForo rating titles and badges.

whenever someone answers on the support forum here, I can see their group, but when I comment in my forum can‘t see my group next to my name. Is there a way to do that in my forum aswell?
Thanks in advance.
