I just bought a house and the back porch lights wouldn't come on. I moved the switch to off position and it tripped the breaker. My master bedroom ceiling lights and ceiling fan are on the same circuit. I put the porch light switch in the on position and I can reset the breaker then. I swapped out the light switch, it has two black wires on the right side and 1 red on the left. There are 5 surface mount lights on the back porch, I've taken two down so far and they have 1 white, 1 black and 1 bare copper wire going to them. I don't know what else to do. The house was built in 2006.
