Why won’t my Yongnuo YN-560 III fire from an RF-603II on a Canon T5i hot shoe?

I’m using a Canon Rebel T5i, a Yongnuo YN-560 III flash, and RF-603II triggers. The flash can be fired with the trigger’s test button, so the trigger and flash seem to communicate, but pressing the camera shutter does not fire the flash from the hot shoe trigger.
The flash and trigger are on the same channel, and the flash is in manual mode. I’m relying on the YN-560 III’s built-in receiver, so there is no trigger mounted under the flash.
What settings or setup steps should I check to make sure the camera can fire the flash through the RF-603II?

Try removing the trigger from the camera hotshoe, and connecting it while both camera and trigger are switched off. Screw the thread down properly, then turn on the trigger, then turn on the hotshoe.
Also, the flash won't fire i think if any sort of silent shooting mode is enabled in Liveview, so if you are using Liveview, there is an option in one of the menus to set 'Liveview silent shooting' to disabled, or Mode 0: off or something along those lines

Generated from our catalog & community — verify before relying on it.
Since the test button fires the flash, the radio link basically works. The likely issue is setup or mode.
Check these first:
- Mount the RF-603II on the camera with both camera and trigger powered off, tighten it fully, then power up the trigger first and the camera/flash after.
- If using Live View, disable silent shooting; on Canon bodies this can prevent flash firing.
- On the YN-560 III, make sure its built-in receiver is set to RF-603 compatibility, not RF-602.
- Put the flash in radio receiver/slave mode (RX for RF), not optical slave modes like S1/S2/Sc/Sn.
- Confirm channel settings match exactly, including the RF-603II dip switches.
- Verify the flash is in the correct group if group selection is being used.
- Use fresh batteries in both flash and trigger.
- For the on-camera RF-603II, if in doubt set it to TX so it simply transmits when the shutter is released.
Because the trigger’s test button works, this is probably not a hardware failure but a mode/contact setting issue.
