We have recently installed Xenforo and have it in its test phase before we transfer all of our members. There's a few things I am getting to grips with in XF but one issue is quite frustrating.
I am trying to change the colour of different user groups depending on their group (ie Administrators have red usernames, lead moderators have green, etc). Now I have already searched for an answer to this and everything I find leads back to User Group Styling (http://xenforo.com/help/user-group-styling/).
I have followed that to the letter, and still the usernames in the various groups are blue.
Administrative has User Name CSS: color: red;
but admin names remain blue.
Moderator has User Name CSS: color: purple;
but still remains blue.
