my login.php says I have an incorrect password, when it is correct ONLY ON GODADDY

Question

When I try to login in my localhost with XAMPP, there is no error, the log in is successful BUT when I try to log in on the internet (with godaddy) here, it redirects me to the error I created called "http://cosmoonlamps.com/ecom/public/login.php?error=wrongpass" in the header. Please help I am a beginner at this stuff so any help would be much appreciated.

<?php 
session_start(); 

if(isset($_POST['submit'])){
  require 'database.php';

  $username = $_POST['username'];
  $password = $_POST['password'];

  if (empty($username) || empty($password)) {
    header("Location: login.php?error=emptyfields");
    exit();

  }else {
    $sql = "SELECT * FROM users WHERE username = ?";
    $stmt = mysqli_stmt_init($conn);
    if (!mysqli_stmt_prepare($stmt, $sql)) {
      header("Location: login.php?error=sqlerror");
      exit();
    } else {
      mysqli_stmt_bind_param($stmt, "s", $username);
      mysqli_stmt_execute($stmt);
      $result = mysqli_stmt_get_result($stmt);

    if ($row = mysqli_fetch_assoc($result)) {
          $passCheck = password_verify($password, $row['password']);
          if ($passCheck == false) {
            header("Location: login.php?error=wrongpass");
            exit();
          

          } elseif ($passCheck == true) {
            session_start();
            $_SESSION['id'] = $row['id'];
            $_SESSION['username'] = $row['username'];
            header("Location: ../../successful.php?success=loggedin");
            exit();
          } else {
            header("Location: ../index.php?error=wrongpass");
            exit();
        }
      }else {
        header("Location: login.php?error=nouser");
        exit();

      }
    }
  }
}else{

header("Location: login.php?error=accessforbidden");
  exit();}
