  • Assuming that the code you posted is from the file C:\xampp\htdocs\dev1\freelance\app\core\Controller.php, I think it could be helpful if you highlighted the lines 245, 246, 250 and 251. Commented Sep 13, 2022 at 5:35

  • Sorry I didn't notice before. The error is ocurring every time you try to access $data['user']['userid'] and by the message of the error, it looks like $data['user'] is null. The problem is most likely in line 240, $user->data() is returning null. Commented Sep 13, 2022 at 5:42
  • Any idea on how i fix this? Commented Sep 13, 2022 at 5:48
  • I can tell you where would I start. I would go inside the data() function of the $user object and debug it. There is probably some sort of mistake or error inside that function that causes it to return null. Commented Sep 13, 2022 at 5:54
