GFCI Risks? Update

Feed through function has failed. Replace the GFCI.

I replaced the GFCI receptacle with an ordinary receptacle and the GFCI fault is still somewhere in that circuit. (the trailer still pops the stick house GFCI)

I expect the fault is where some wire insulation has come away from a white wire going into a receptacle and it is touching the frame or some kind of thing like that which will be hard to find.

I get two lights on the receptacles for "normal" so that says there is a ground ok. So is the safety feature of the "three-prong plug" still in effect even though somewhere in the circuit there is a GFCI fault? What about the two- prong plugs that have one fat prong? Ok?

Any risk at all?
