Hi, hopefully someone can help me because we are stumped. This is the fifth light we have changed out in our house but the first with issues. We removed a ceiling fan that was original to the home. In the box there was a single white, a single black and a white/black twisted together and the copper ground wire.

On our new light fixture (chandelier) there is a copper, black with writing and smooth black.

Originally we had the copper from the fixture and the ground copper wrapped together under the green screw on the mountain bracket. Then we had the ribbed wire with writing on it wrapped with the single white (as the instructions said) and the smooth wire from the fixture with the single black. Then we were not exactly sure what to do with the white/black that were twisted. So we capped it off, restored power... nothing. How do we wire in the twisted ones?

There is only one switch that controlled the light. There are two other switches on the same place by the door and both of the other switches work fine when power is restored. What are we doing wrong?

The wiring as you have described it, is correct. The black of the black of the black/white connection is bringing power to the ceiling box. The white of the black/white connection is taking that power to the switch. Single white is the neutral. The single black is returning power from the switch (when switch is on).
So the ribbed from the light to the white neutral is correct. The other wire from the light to the black is correct.

Most likely fault is probably a bad connection in the black/white connection. Could be a faulty switch but unlikely.

The white and black need to be connected in the box as it was, also put black tape on THAT white to identify as hot going to your switch, and comes back up on the Black, this goes to your fixtures black.
Connect the black with white writing to the white wire at ceiling, I believe it is your Neutral(white), I would verify with continuity tester or meter that the black with white writing has continuity with the threaded, more exposed part of the fixture.

OK, so ribbed from the chandelier to white and smooth wire from chandelier to the black. Got it. How exactly do we tie in the twisted wires into all this? That's the part that's confusing me. Do they need to remain twisted and go to the single white? Remain twisted and go to the black? Separate?

Each socket needs to connect to the Black and the white.

They are simply twisted together and capped with a wire nut. Which you said you have done. You probably just didn't get a good connection. This is said with the assumption that you did not get your wires mixed up.

Ok. We'll cap the twisted back off, connect the white to the ribbed one without writing, and the smooth one to the black wire and try again. Fingers crossed.

Success!! Thank you all so much!
