Clarification on Permission of Approval Ticket

I already followed what is stated on
but couldn’t make the my approval link works. Nothing is
displayed even I selected pending, approved, denied, etc.
The approval ticket is created already. Is there other
permissions I need to check aside from giving the AdminCC
the show ticket (even Ienabled everything).

Note: This happened only after I upgraded from 3.0.5 to 3.4.5.
