[問題] easymode + attachment mode 無法執行

[kevet]

小弟安裝 appach 2.4.4 a + Php 2.013 + easy mode 0.21 beta 1 + Attachment mode 2.3.1.3

小弟 follow Man520 大大的教學方法

安裝 easy mode 後沒有問題
但在控制台執行外掛 attachment mode 後
出現錯誤訊息\r
Warning: main(./attach_mod/attachment_mod.php): failed to open stream: No such file or directory in c:\appserv\www\phpbb2\common.php on line 226

Warning: main(): Failed opening './attach_mod/attachment_mod.php' for inclusion (include_path='.;c:\php4\pear') in c:\appserv\www\phpbb2\common.php on line 226

Fatal error: Call to undefined function: include_attach_lang() in c:\appserv\www\phpbb2\includes\functions.php on line 290

懇請大大門幫忙
