Can you go back and verify that each is correctly wired? Generally, black is hot and goes on the gold (small) connector; white is neutral, and goes on the silver (large) connector. The bare wire is ground, which often goes on a green connector.
One more thing: many of those testers can give you misleading information. You might or might not have a hot and ground reversed.

I even checked the wiring to the light fixture there is current going through the wires but nothing runs when directly plugged to the wires.
I will not disagree with electricbil, but you have an open neutral ! You have a white wire which may or may not be on it's own dedicated bar,loose. As time goes by heating and cooling will expand and contract these wires and they sometimes come loose. It will happen more often if these wires are aluminum. You need to tighten these lugs and all ground lugs as well. There is a chance you might have a loose hot wire on a breaker, but do the neutrals and grounds first. You MUST be very careful not to be grounded yourself or touch anything which will provide a path for electricity to flow...it can be very unforgiving !!
