UCS 5.2 Password Change Self Service Option Missing

Hello, I upgraded UCS to 5.2 an i cant see the change password option where users had the option of entering the username, old password then new password. This is the link to my home page http://10.10.50.237/univention/portal/#/. i have tried adding the self service links in full but they are not working. How can I make it easy for users to change there password? Help will be appreciated.
