안녕하십니까?

제가 집의 PC에 APMSETUP7과 XE를 설치하여 홈페이지를 꾸며 왔으나
속도에 한계가 있으므로 NGINX에 도전하기로 하고
WnMP라는 pacakge 프로그램을 설치하였습니다.

그런데 XE 1.7.3.1를 설치하는 마지막  단계인 "완료"버튼을 누른 결과,
제2항과 같은 내용의 메시지(broswer는 IE9를 사용)가 나타났습니다.

이 문제를 저의 능력으로는 도저히 해결할 길이 없어서
고수님들께 도움을 요청합니다. 감사합니다.

1. 저의 PC 서버의 재원

       1)   Windows 7 home premium k

        2)  WNMP 2.0.1.1의 구성 프로그램

                      Nginx 1.2.8
                      MariaDB 5.5.30
                      PHP 5.4.13 (Non Thread Safe + FastCGI) 
                      phpMyAdmin 3.5.7

2. 웹 사이트에서 페이지를 표시할 수 없습니다. HTTP 500
 
                  가능성이 높은 원인:
                    •  웹 사이트는 유지 관리 중입니다.
                    •  웹 사이트에 프로그래밍 오류가 있습니다.

3.  XE의 tmpDB.config.php파일의 내용

 <?php if(!defined("__XE__")) exit();$db_info->master_db = array('db_type' => 'mysql','db_port' => '3306','db_hostname' => 'localhost','db_userid' => 'root','db_password' => 'xxxxxxx','db_database' => 'xe','db_table_prefix' => 'xe_');
$db_info->slave_db = array(array('db_type' => 'mysql','db_port' => '3306','db_hostname' => 'localhost','db_userid' => 'root','db_password' => 'xxxxxxx','db_database' => 'xe','db_table_prefix' => 'xe_'));
$db_info->default_url = 'http://localhost/xe/';
$db_info->lang_type = 'ko';
$db_info->use_mobile_view = 'Y';

                            *. 죄송합니다. 비밀번호는 x로 칠했습니다.

4.  WnMP 의 error.log 파일의 내용

PHP Catchable fatal error:  Object of class Object could not be converted to string in C:\Wnmp\html\xe\classes\db\DBMysql.class.php on line 590" while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "POST /xe/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost", referrer: "http://localhost/xe/index.php?act=dispInstallManagerForm"

5.  Nginx.conf 파일의 내용 (똑같은 내용을 첨부파일로도 올렸습니다)
