00. 大多看到這問題發生在您用的是 PHP 5.3.0 或使用套裝軟體搭配的 PHP 版本是 5.3.0。

01. 下面為解決的方法, 則一使用即可, 依推薦使用的順序排序。

  1. 修改 ./wp-config.php, 加上

date_default_timezone_set('Asia/Taipei');

  2. 修改 ./wp-includes/functions.php

    a. 在第一個 function 前面加上

date_default_timezone_set('UTC+8');

    b. 在第一個 function 前面加上

date_default_timezone_set('Asia/Taipei');

  3. 修改 php.ini, 加上

date.timezone = "Asia/Taipei"

02. 上面的 Asia/Taipei 均可以替換成下面任一城市, 其它城市請到 PHP timezones 尋找

日本 : Asia/Tokyo
台北 : Asia/Taipei
重慶 : Asia/Chongqing
漢城 : Asia/Seoul
上海 : Asia/Shanghai
新加坡 : Asia/Singapore
澳門 : Asia/Macao 或 Asia/Macau
香港 : Asia/Hong_Kong 或 Asia/Chungking

03. 上面所提到的套裝軟體為 AppServ, PHPnow, XAMPP, WampServer, APMServ, EasyPHP。

02. PHP date_default_timezone_set

1. 找到你安裝 Apache 的資料夾，並進到 conf 資料夾 (default:C:\AppServ\Apache2.2\conf)

2. 用 文字編輯器 (eg:NotePad, NotePad++, Emeditor, UltraEditor ... etc ) 打開 httpd.conf

3.
a. 法一
Ctrl + F 找到 #LoadModule rewrite_module modules/mod_rewrite.so 把前面的 # 去掉
b. 法二
Ctrl + H 取代 目標 #LoadModule rewrite_module modules/mod_rewrite.so
取代 LoadModule rewrite_module modules/mod_rewrite.so

4. 用上面的方法把 #AccessFileName .htaccess 前面的 # 去掉 ( 有的default就去掉了 )

5. Restart Apache Server, Done! // 我按Restart沒有用，按 Stop 再按 Start 才成功
