Hello all, I need your help

i want to display a user list, and when a person log in into community builder, he can click on his name in user list. But my problem is when a person after logged in and click his name in user list, it does nothing. And when he tries to view his profile from another person's profile, it is same, nothing change.

Thank you for your help all

It's better if you give details: joomla version, cb version, (perhaps template)
Do you have a menu point profile (mandatory) and can reach your profile in a normal way?
