I'm having problems with my GX7 using an external flash (both the FL-360L and Cactus V5 Triggers). First, camera is not in silent mode. Both camera and flash recognize that something is attached to the hotshoe, but will not trigger anything. The flash symbol keeps showing as red. I can use the popup fine, and even use it to trigger the FL-360L remotely. Also attempted a reset of user options from the menu setting. Nothing changed except for all of my custom settings... which I had to go change again. Any thoughts?
