Hi There, The white wire (pigtail) that was pulled loose needs to be connected to the other white wires inside the box. . After that connect the black pigtail (that is hanging loose) and white pigtail to the eterminals on the light fixture. Hope that helps, Al
Your fixture is wired as a switch loop. Power comes in at the ceiling box and continues onto other parts of the circuit from there as well. One of the pairs of wires is for the switch. The cable containing the black wire that went to the fixture also contains the white wire that is HOT and is connected to the remaining black wires. All the remaining white wires are neutral and need to be connected together with a wirenut. But before connecting them, also include a white 14-gauge pigtail with the connection. Use a beige or red wirenut. Yellow will be too small. After you've made the wiring connections, simply connect that white pigtail to the white wire of the fixture, and the black wire to the black.
