Continuity mistake: The furniture used throughout the show regularly gets blown up or destroyed but then mysteriously re appears later on or in the next episode.
A Wrong Day's Journey Into Right - S6-E20
Revealing mistake: Right after Paige is orbing out, the camera is on Phoebe and on her right, you still see Paige's shoulder. And then it cuts to Paige orbing back in.
Factual error: During the ritual, we can see that the snake that is magically transformed into a man is a milk snake. But it's not poisonous, it's a colubrid. The creators apparently wanted to use its resemblance to a poisonous coral snake, which is an elapid. (00:02:35)
Continuity mistake: When Paige is at the bar with her newest charge we see the same extra walk by 3 times, going the same direction each time.
I've Got You Under My Skin - S1-E2
Revealing mistake: At the end of the episode when Phoebe and the other two are at the bar you can notice that Prue straw in her drink goes in and out of her drink a great deal.
Continuity mistake: When Prue lets Matthew out of the locket, the front view Prue has her right hand on her stomach, when the shot changes to the back view her hands are by her side, it does this multiple times.
Something Wicca This Way Goes - S7-E22
Continuity mistake: When Zankou is looking at the spell in the Book to steal TCO powers we see that it is the same spell Aunt Gail used in "How to Make a Quilt out of Americans", except that in that episode she ripped the page out of the book. It shouldn't be there for Zankou to use. (00:09:56)
Visible crew/equipment: When Piper is coming down the stairs with the staff, if you look in the top left corner of the stairs, you can see a piece of camera equipment moving.
Love Hurts - S1-E21
Continuity mistake: Leo dies and then Piper heals him. In all future episodes it's made very clear that Leo's powers can't heal the dead.
Charrrmed! - S7-E4
Continuity mistake: Baby Chris doesn't have a binkie in his mouth, then does, then doesn't. (00:39:23)
Witch Wars - S6-E21
Plot hole: In the beginning of the episode the opening screen row Witch Wars has images of the witch Paige saved before the event actually occurred.
Which Prue Is It, Anyway? - S1-E16
Continuity mistake: When Prue goes up to cast the spell, Piper and Phoebe are downstairs and Piper's hair is down. When they hear the effects of the spell they run in to the attic and both say "Oh my god!" one after the other and Piper's hair is now slicked back in a ponytail.
Continuity mistake: When Chris and Bianca go to the manor to get Chris to go to the past, which would end up him appearing in "oh my goddess"; he's only wearing a black shirt and pants. When he arrives to the past in "oh my goddess" he's wearing a jacket, red shirt, and sunglasses. He wasn't wearing that in Chris-Crossed. And he didn't have time to change to that outfit.
The Last Temptation of Christy - S8-E15
Visible crew/equipment: At the start, Piper tells Billie she needs to be patient with Christie, and when Piper adds that if Billie needs anything they are just a call or an orb away, the pink tape mark is visible on the floor at Billie's feet. (00:01:10)
Visible crew/equipment: After orbing into the manor's attic Paige reveals to Rohtul that she switched identities with Billie, then when the real Billie walks out and joins the sisters, we can see the pink T-mark at the bottom of the screen. (00:39:35)
Visible crew/equipment: At the bank, when Nick gets off the phone after talking to his son he walks around the stanchion, and as he says, "I never wanted to hurt anybody," we can see the light green T-mark on the floor where he had been standing. (00:29:15)
Visible crew/equipment: When the smoke alarm starts blaring at the manor JD freaks out, and as he runs out of the door the reflection of a crew member wearing shorts is visible on the glass door. (00:23:05)
Continuity mistake: After Antosis and the Imp Master are vanquished, in a following shot we see Phoebe wearing a robe and sitting on the bed, then we see her "Julie Bennett" reflection in the mirror, but notice that even though the style of the robe is the same, the colorful designs are quite different in the reflection. This happens again later when the sisters and Leo are seen in the mirror's reflection, as they undo the spell to reveal their true selves. (00:33:25)
Continuity mistake: After the opening credits, while Piper tries to persuade Paige to help with the speed dating at P3, in two shots facing the bed and in the shot facing the mirror showing the "Jaime and Jo Bennett" reflection, the lamp on the far side of the bed is turned on. When Leo is holding Chris he walks past the mirror, and in this reflection that lamp on the far side of the bed is turned off, but in the next shot facing the bed that lamp is on again. (00:04:55)
