請問在安裝mediawiki時的語系選擇是不是要先選英文再來作中文化的動作呢? 我的伺服器狀態採用The AppServ Open Project - 2.5.4a for Windows

1. Apache Web Server Version 2.0.54
2. PHP Script Language Version 5.0.4
3. MySQL Database Version 4.1.12a
4. phpMyAdmin Database Manager Version 2.6.2-pl1

當我用選擇utf8時安裝過程出現下列的錯誤訊息

   * PHP 5.0.4: ok
   * PHP server API is apache2handler; ok, using pretty URLs (index.php/Page_Title)
   * Have XML / Latin1-UTF-8 conversion support.
   * PHP is configured with no memory_limit.

請問我要如何修正這個錯誤呢?
