Sidebar not showing

Hi, I am developing an app following instructions from a yt video. When I start the streamlit server locally the main page shows ok but on the sidebar there seems to be a problem with Signup page not showing, however the Login page shows just fine. Any ideas?

Hi,
please post the code.

You got a typo, first you write “Singup” then “SignUp”
