關於與phpbb整合的問題

[shukai]

各位好
我安裝lifetype1.1.1並且把userdata.properties這裡改成
#$config = Array(
#  "provider" => "LifeTypeUserDataProvider",
#);

#
# PHPBB2 user data provider
#
$config = Array(
  "provider" => "PhpBB2UserDataProvider",
  "createBlogIfNotExisting" => true,
  "database" => "phpbb2",
  "user" => "shukai",
  "password" => "5168",
  "prefix" => "phpbb_"
);

其中user那邊是已經在mySQL新增的使用者，權限同root

先裝好phpbb
然後開始裝lifetype

問題在輸入完admin的資料後next
就跑出"Fatal error: Cannot instantiate non-existent class: userinfo in C:\AppServ\www\lifetype\wizard.php on line 1080"

請問這會是怎麼回事呢?
謝謝您的回答
