When I used the circuit tester to check my house's circuit, it reads on a couple of the outlets "open ground." There is no third wire ground on the wiring. Only a hot and a neutral. What does that mean and how do I go about fixing that?
But all the others in the house are okay and read correct. The house was built in the 1950s. About 10 years ago, I had the fuse box upgraded to a circuit breaker box. Any help would be appreciated.

Reason: I added a bit more information.
Here's another thing to consider. If these receptacles are in steel boxes that are fed with either emt or BX cable, we could be looking at a poor/loose connection between the cable armor/conduit and the box connector. With conduit, I've seen instances where a loose locknut could be enough to break the bond (and once the plaster ring is on, they can be a bee-ahtch to get at with a tool).
Well, now, there's what's right and what's right and never the twain shall meet.
