ok, so i want to verify the hashed password stored in my database; however everytime i implement password_verify i get the white screen of death. But when i remove it and use a password that isnt hashed in the database the script works.

i turned on error reporting in both my config files and the script itself

<?php

   ini_set('display_errors', 'On');
   error_reporting(E_ALL | E_STRICT);
   session_start();

     include('config.php');


  // if($_SERVER["REQUEST_METHOD"] == "POST") {
      // email and password sent from form 
     if (isset($_POST['email'])) {
        //do something

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

   }
   if (isset($_POST['password'])) {

      //$password = $_POST['password']; 
      //$password = password_hash($_POST['password'], PASSWORD_DEFAULT); 

   }

    $conn= new mysqli ("$DB_HOST", "$DB_USER", "$DB_PASSWORD","$DB_NAME");

      $db="ship2two4_a53";
      $sql = "SELECT * FROM usersdb WHERE email = '$email' AND password = '$password' ";
       mysqli_select_db($conn,$db); 
      $result = mysqli_query($conn,$sql);

      $row = mysqli_fetch_array($result,MYSQLI_ASSOC);
      $active = $row['active'];

      $count = mysqli_num_rows($result);
     // implode($row);
      // If result matched $email and $password, table row must be 1 row

      if($count==1) {
        // session_register("email");
         $_SESSION['email'] = $email;


         }

         if(password_verify(  $_POST['password']  ,$password)){



header("Location:../sbAdmin/index.php");

}
      else {
         $error = "Your Login Name or Password is invalid";
      }

   mysqli_close($conn);
?>

i want the script to run and the user be sent to their dashboard
