Forcing HTTPS on the domain disables website functions

[Larry]

Hello, recently I forced HTTPS on my domain and it disabled the menu buttons on my homepage. I have been trying to find which files to edit to change the URL. I keep searching my server to find the file that controls this. I found a file that looks like a config file, and wondered if this is it. Can anyone advise?

<?php
function __getConfig() {
    if ($_SERVER['HTTPS'] == on)
        $protocol	= "https://";
    else
	$protocol	= "http://";

    if (substr($_SERVER["HTTP_HOST"], 0, 4) != "www.") {
	header("Location: ".$protocol."www.".$_SERVER["HTTP_HOST"].$_SERVER["REQUEST_URI"]);
        exit();
    }

    return array(
        'base_url'          => $protocol . "www.luxurybeach.com/admin/",
        'base_href'         => $protocol . "www.luxurybeach.com/",
        'appname'           => "Luxury",
        'GD'                => extension_loaded('gd') || function_exists('gd_info'),
        'manifestRealName'  => "js/FAQ-file-manifest.json",
        'manifestName'      => "front/JSONmanifest",
        'storageName'       => "LuxuryBeach_ManagedStore",
        'update_center_url' => 'http://dev/sergey.ostapenko/updatecenter/checker/index.php',
        'tablePrefix' => ''
    );
}

function __getDBConfig() {
    return  array(
        'hostname' => "localhost",
        'username' => "luxury",
        'password' => "plzleavemealone",
        'database' => "luxury",
        //'database' => "faq",
        'dbdriver' => "mysql",
        'dbprefix' => "",
        'active_r' => TRUE,
        'pconnect' => FALSE,
        'db_debug' => TRUE,
        'cache_on' => FALSE,
        'cachedir' => ""
    );
}
?>
