@faizanzahid Those in the screenshot are the global privileges. You want to change the category privileges, selecting each category (see up to the right), at least the root ones. There is also a button to copy privileges to the children categories.
SOLVED How do you show a user's group next to their name?
Is there a settings option or plugin which enables the group to be displayed next to a users name? For example, in this post user pichalite is in the 'PLUGIN & THEME DEV' group. I have several users in groups on my board but their groups are not displayed next to their name as above. Is there a special way to enable this?
Within your user settings within the category Groups you may select a group label.
