codeigniter 2.2.0与A3M在远程服务器上无法正常工作

Question

in my new project i am using codeigniter 2.2.0 and A3M 1.01 authorization library i have checked on my localhost it is working fine but when i uploaded it on remote server, home page is loaded but sign in is not working it shows following error( www.redzoon.com )

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [e-mail] 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.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request." i contacted the server administrator he said there is some problem with application. so i thought there may be problem in .htaccess file. this is my .htaccess file code

   RewriteEngine on
   RewriteBase /CodeIgniter2.2_A3M/
   # Directs all EE web requests through the site index file
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule ^(.*)$ ./index.php/$1 [L]

   <IfModule !mod_rewrite.c>
       ErrorDocument 404 /index.php
    </IfModule>

please help me where am i doing wrong, is there anything i have missed

Answer 1

i have googled for about three days finally i got some clue by changing .htaccess. now i was not getting 500 internal server error instead i was getting "no input file specifed" then i searched again about this error and i found a link .htaccess problem: No input file specified where i got solution to my problem this is the .htaccess code

DirectoryIndex index.php

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php|robots\.txt)

RewriteRule ^(.*)$ index.php?/$1 [L]

this worked for me.
