How to allow users to change username?

I am new to CB. I have users asking how to change their usernames. When logged in their profile is not accessible. I can change it in the back end but users can't change in front end. Even logged in as super admin I can't access my profile page in front end. I do, however, have a test profile that I can access the profile. It's the only profile that can be accessed on the frontend out of the 100 plus users on my site. When logged in, there is no link to view profile or anything like that, just says "Hi, (username).

Any suggestions?

I do have the Allow user to edit his CMS parameters in frontend selected as "yes"

Thank you!

Two suggestions ..

one become an advanced member and read the manual

two - look at the CB Configuration User Profile Tab.

What do I look for in the user profile tab? Everything that I think should be ok, looks ok...still nothing.
