Factual error: During the Song "Never Had A Friend Like Me", Genie the waiter is writing an order in Arabic, but he writes from left to right. Arabic is written from right to left.
Stupidity: When Jasmine finds out that Prince Ali is actually the boy she met in the marketplace, she seems to completely forget about Jafar telling her he had been executed. She never asks why he's alive, nor does she even bother to confront Jafar about his treachery.
Suggested correction: The fact Aladdin was alive only told her Jafar lied about it. When she is brought back by Aladdin to the palace it is still night, not long after that she is confronted by her father and Jafar who has him under a spell. She hardly had time to ask about the treachery, probably thinking to do it in the morning. It is there and then Jafar is exposed by Aladdin. She probably wondered about it, but didn't figure out the implications yet.
Continuity mistake: When Jasmine wanders by the market and is shown a fish, the fin is either perpendicular or parallel to the body depending on the shot.
Suggested correction: This is simply not true, it's seen in only 2 shots and both the pelvic and the dorsal fin stay the same size, the fish is further away in the second shot and the pelvic fin changes position and looks a different size but they use the exact same drawing. Even so, the dorsal fin of a fish can change size even when dead and shaken about by the salesman. And the tail fin is only seen in 1 shot.
