用steam登录返回白页？

Question

On my website I have a login with steam feature, upon signing in on the steam end of this process, people are redirected to a white page, rather than the home page, also, the sign in data is never sent to the server, I've tried reading through my code but I can't seem to find why this problem is occurring.

settings.php

    <?php
$fileLoc = $_SERVER['DOCUMENT_ROOT'] . '/../passwords.txt';
if (file_exists($fileLoc)) {
    $fh = fopen($fileLoc, 'r');
    $jsonStr = fgets($fh);
    $arr = json_decode($jsonStr, true);
    $apiKey = $arr['steamAPIKey'];
    fclose($fh);
} else {
    die('no file found');
}

$steamauth['apikey'] = $7456B63D1E2C9CAFC06ACF35D97E1D9C; // Your Steam WebAPI-Key found at http://steamcommunity.com/dev/apikey
$steamauth['domainname'] = "http://www.csgoexcite.com/"; // The main URL of your website displayed in the login page
$steamauth['buttonstyle'] = "large"; // Style of the login button [small|large_no|large]
$steamauth['logoutpage'] = "index.php"; // Page to redirect to after a successfull logout (from the directory the SteamAuth-folder is located in) - NO slash at the beginning!
$steamauth['loginpage'] = "index.php"; // Page to redirect to after a successfull login (from the directory the SteamAuth-folder is located in) - NO slash at the beginning!

// System stuff
if (empty($steamauth['apikey'])) {die("<div style='display: block; width: 100%; background-color: red; text-align: center;'>SteamAuth:<br>Please supply an API-Key!</div>");}
if (empty($steamauth['domainname'])) {$steamauth['domainname'] = "localhost";}
if ($steamauth['buttonstyle'] != "small" and $steamauth['buttonstyle'] != "large") {$steamauth['buttonstyle'] = "large_no";}
