Continuity: When Lizzie attempts to confess to Kate in the hallway she is wearing a red and white shirt with no bag. However in one shot from behind, you can see that there is a blue bag strap over her left shoulder. This is the same blue bag she can be seen wearing in later scenes.

Plot hole: When Lizzie and Gordo are sitting at lunch, Gordo says that he doesn't like broccoli (refering to the pile on his plate) and that he tries to avoid it. However it is established in many scenes that Lizzie's school has a self serve cafeteria, so why does he have broccoli?

Visible crew/equipment: When Lizzie enters the gymnasium to confrontate Kate about what she sent via the instant message, as she stops in front of Kate you can see the nice, big red tape mark at her feet.

Revealing: When Kate opens her locker, a mountain of toilet paper falls out of her locker due to a prank played by Miranda. However if you look closely you can see the hand of a crewmember pushing the mountain of toilet paper out of the locker.

Continuity: When Lizzie and Gordo are sitting at lunch, Gordo is sitting there playing with his fork. But then when Miranda comes over to sit down with them, Gordo now has his arm down on the table and is no longer playing with his fork.

Visible crew/equipment: After the McGuire's dig back up Lizzie the lizard; as they walk across the garden (with Mrs. McGuire telling Matt that he should open the box) if you look from the point where they began to walk from, you can see a white tape marker on the ground.
