Run CI under Wordpress root directory

Hi,

My name is Martin Contreras, I have a similar problem.

My structure in Amazon linux ami is

var/www/html/

web ---> main web in wordpress
demo ---> ci application
caz ---> another web in wordpress
index.php --> redirect to web

My problem is codeigniter is not working without index.php although $config['base_url'] = '' and my .htaccess in demo folder is like this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /demo/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /demo/index.php [L]
</IfModule>

wordpress web htaccess

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /web/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /web/index.php [L]
</IfModule>

Web works well but codeigniter demo project dont working

Not Found

The requested URL was not found on this server.

Only works if I put index.php

Thanks in advance

Martin
