I can't load page

Hi everyone.
I have a problem when loading page whit php.

it is supposed that it has to load when the query throws a result, but it does not load only it shows me the code in the tools for chrome developers and I do not know what it could be.
I leave the code and images

<?php session_start(); include ("conex.php"); $usuario = $pass = ""; $html = 0; if ($_SERVER["REQUEST_METHOD"] == "POST"){ $usuario = mysqli_real_escape_string($con,$_POST['user']); $pass = mysqli_real_escape_string($con,$_POST['pwd']); $sql = "SELECT id_congregacion, nombre_hermano, apellido_hermano FROM hermanos WHERE user = '$usuario' AND pass = '$pass'"; $result = mysqli_query($con, $sql); $row = mysqli_fetch_array($result, MYSQLI_ASSOC); if (mysqli_num_rows($result) >= 1){ $_SESSION['login_user'] = $row['nombre_hermano']." ".$row['apellido_hermano']; $_SESSION['congregacion'] = $row['id_congregacion']; header("Location: ../html/inicio.html"); mysqli_free_result($result); }else{ $html = 1; } } echo $html; mysqli_close($con); ?>
