Wayne this is one of only three things.

1. Ground/neutral connection: Look for a bare ground wire touching a neutral at a device

2. neutral of the wrong circuit being used ether at load end or at the breaker end: Check which wire is on the breaker and load end

3. Shared neutral with two circuits: You cannot share a neutral unless you use a two pole AFCI breaker. Just like a GFCI circuit.

I agree with Hurk, in the three types of causes it may be. When pushing the device back into the box, sometimes the bare equipment ground conductor will be directed towards and make contact with the grounded conductor of the device. Also the fixtures may cause the same problem.
Good Luck!!
