Hello, this is my first post here.
I called session_start() on both pages right at the top, and yet when I load the other page that same session variable “user” (when I echo it) seems to be null and doesn’t execute the if else statement, I’ve been at this for two days now, really stuck.
session_id is set and the same on both pages, session_status() is 2 (active, but no one exists).
Here is my code:
I put it codepile, until I format this correctly, so sorry for the edits
