Who Me Too'd this topic

I feel really dumb, but I don't get it. I shoot video so I usually have no use for a flash, but today Ineeded to take pictures and I couldn't get it to work. I figured out that it only works whenI'm not in live view. I read something in a forum about turning off some setting, but doing so didn't not fix it. Canon can't be that stupid, so it must be me.
