Continuity mistake: When Leo comes to the manor to tell Piper about Masselin, during the conversation Prue is not wearing her choker in the shots facing her (with her arms crossed) and Phoebe, but in the next shot when Leo tells Piper that he knows she's upset we see Prue's choker suddenly around her neck. (00:11:50)
Visible crew/equipment: After Prue gets off the phone with Barker and tells Phoebe about it, when Piper runs into the kitchen with the news about Dishwalla, the reflection of the moving boom pole can be seen on the glass cabinet. (00:10:00)
Visible crew/equipment: While Phoebe begins her "fifteen minutes of channel surfing" she has the burning premonition and cries out, then in the next shot as Prue and Piper rush in, we can see the reflection of the boom mic/pole in the wall mirror. (00:02:10)
Witch Trial - S2-E1
Visible crew/equipment: While the Book of Shadows flips its pages the sisters enter the attic, and after Piper asks how the book does that, in the next shot the feet of a crewmember can be seen moving quickly out of shot, at the bottom left side of the screen. (00:03:15)
Visible crew/equipment: When Piper is taken by Wong's men Mark shouts for help, and just as Prue tells Phoebe to call 911 from the car, the blue tape mark is visible on the rug beside the table, where the sisters had been standing before rushing out. (00:36:05)
Visible crew/equipment: When Prue is flicking through TV channels, just as Phoebe walks into the bedroom and stands beside her sister, we can see the movement of the camera operator and camera in the reflection within the standing mirror, near the door. (00:34:05)
Visible crew/equipment: After Piper takes the picture of Tony Wong holding the newspaper, when she and Mark quickly drive off, we can see the actors' large yellow T-mark taped to the ground near Wong and his men. (00:28:35)
Visible crew/equipment: When Aviva tells Phoebe that she wants to go upstairs because she's not feeling well, Aviva walks into the bedroom and just as she grabs her backpack part of the T-mark is visible on the floor where she stands. (00:33:45)
Wicca Envy - S1-E10
Visible crew/equipment: After Jaime tells Prue that she's the hardest working woman he's ever met and believes she's innocent, Prue walks into the office to access Hannah's computer, and just as Prue sits down and moves closer to the desk, the blue T-mark is visible on the floor, under the office chair. (00:24:30)
From Fear to Eternity - S1-E13
Visible crew/equipment: When Andy walks into the manor to speak with Prue, just as she tells him it must be bad news, we see the reflection of the boom mic on the glass door. (00:09:45)
The Wendigo - S1-E12
Continuity mistake: When Andy is lying on the ground unconscious The Wendigo rips open his shirt popping all the buttons, but in the closeup of Andy's face his shirt is still buttoned up. (00:38:50)

Visible crew/equipment: When Phoebe joins her sisters in the kitchen before her first day at work, the reflection of the moving boom mic is visible on the glass cabinet, at the top of the screen. (00:10:05)
Which Prue Is It, Anyway? - S1-E16
Continuity mistake: While Phoebe explains the slam man training system Piper puts on Phoebe's boxing gloves, and when Prue says that demons don't play fair Piper playfully raises her left arm to Prue's forehead, but in the next shot facing Prue it's Piper's right arm that's raised. (00:04:00)
Continuity mistake: While Andy and Darryl are at the station talking about why Andy's been "walking around...like a zombie," Andy places a pencil behind his ear, but when it cuts to Inspector Blakely walking in behind Andy the pencil has vanished between shots, but it reappears again in the next shot. Then when Andy borrows the photograph of the knife, once again the pencil vanishes between the closeup and wideshot. (00:09:10)
Chick Flick - S2-E18
Character mistake: After the horror movie characters were killed in the attic, the sisters hear the door bell ringing. When they get to the bottom of the stairs and start walking towards the front door, you can see the actor playing Billy smiling even though they're all supposed to be on edge.
Revealing mistake: The sound of Phoebe writing with a permanent marker was added in, as you can see that the marker never touches the paper. Then after a few seconds Phoebe stops writing to listen to Prue and her marker isn't moving but the sound of writing can be heard. (00:05:30)
Plot hole: When Yen lo enters the manor in the attic. Where did the water on the floor he comes through come from? Windows were closed, no visible leak, and the sister took precautions to make sure there was no water in the house. Also after he attacks and gets the dragon blade, he exits the house through the sink filled with water. Piper had already said to make sure there was no surfaces of water in the house and had Phoebe and Paige shut the water main off.
Suggested correction: There is a previous scene that shows a visible leak in the windows and an obvious puddle of water on the floor of the attic. This is the same puddle they later enter limbo through. As for the sink, Phoebe (in Paige's body) explains that she had been soaking potion pots and forgot to drain the sink. Turning off the valve wouldn't dissipate water that is already in the sink.
Factual error: Phoebe is going to be burned at the stake for witchcraft like they're starting the Salem witch trials again, but witches weren't burned, they were hanged.
Plot hole: When the man and woman receive Piper and Phoebe's powers, the lady freezes the man and Phoebe due to fear, but good witches don't freeze, so if Phoebe froze (which she shouldn't have due to only her active powers lost) then why did the man? If he had Phoebe's powers then he isn't mortal and therefore should not freeze.
Plot hole: When the Avatars agree to rewind time they say that they can either put the world right or save Brody but not both. This doesn't make sense since they're rewinding to right when they put everyone to sleep, which is before Brody was killed.
