Updated NGUI, cannot click buttons anymore ?

[Tester1234]

I have updated latest NGUI version from asset store, I cannot click any button anymore ( it was working fine, using Unity 5.3.2p4 ), However if I add new button to scene, it creates another UIRoot and adds button there, and that buttons work, but my old buttons in my old UIRoot does not work ?

Any idea ?
Thanks

Check your UICamera's event style. It should be 3D UI, not 3D world.
