Error in the "Predict" Section

[SabbyDude]

Whenever I put a Ticker Value and no. of days, it either loads an error page which reads:
DataFrame.drop() takes from 1 to 2 positional arguments but 3 were given

or

A 404 error page that is made by you, even though the names are correct

[Infinity2304]

i am getting a key error for "Adj Close"

[Infinity2304]

is there any solution ?
