請問關於cakephp的配置有關問題

請教關於cakephp的配置問題
我是按手冊進行的配置，在apache的伺服器設定檔上設定了documentroot "e:/cakephp/app/webroot"，然後了這樣倒是可以訪問webroot/index.php。但是手冊上說還要設定幾句

Options FollowSymLinks
AllowOverride all
# Order deny,allow
# Deny from all

AllowOverride all本來是AllowOverride none
但是設定為ALL之後程式就出錯了如下
/-------------------------------------------------------------------/
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.
/-------------------------------------------------------------------/
請問是什麼原因，還有就是修改了webroot/.htaccess，請問這有什麼用？？？？？？


------解決方案--------------------
應該是webroot/.htaccess 這個檔案的錯誤，把這個檔案的配置貼出來看看
代碼迷推薦解決方案：The server encountered an internal error () that prevented it from fulfilling this request.,http://www.daimami.com/java-web/317.html
