Ushahidi - トップページ以外が404になる場合の対処法

httpd.confで以下を確認

AllowOverride All

open application/config/config.php

in this file ...
make :
$config['index_page'] = 'index.php'; line 21
$config['url_suffix'] = '.html'; line 26
in my case these 2 were blank

also ensure that the
$config['site_domain'] = 'yoururl/'; don't forget the final slash

also check .htaccess
in this one u should just have
# Installation directory
RewriteBase /YOURDIRECTORYNAME/ (notice the final slash)
