Display button not working for ESS Family Member/ Dependent

Hi all,

After upgraded to EHP5, ESS Family Member/ Dependent is not working.

At the first screen, i am able to see all the family members.

The problem arises,

when i select a member and click on the Display button.

Nothing change, the page remain the same.

The display button should bring me to another page instead.

Anyone has encountered this problem.

Thanks in advance

Regards.
