Hi experts,
PBCS:
I need help, I am trying to get back to the Standard Interface in PBCS but unable to... previously when we received the instance, we are still accessing the standard interface, after one weekend it suddenly always opening the Simplified Interface.
What I tried:

- Remove the application and recreate -> Even the application creation page is in simplified now
Seems very simple but I can't find the menu....
Could you help me on how to get back to the Standard Interface?
Thanks
