CodeIgniter Config / htaccess

[eluser]Dirigible[/eluser]
Hi all,
I recently got my site to work on my local server to develop on. However, when I committed the changes to my test server, several things broke. I tried to reset the test server ... breaking more things in the process. I am now in a rut, and would like any guidance at all possible.

Here's my test server folder structure: /html/test/myapp/system/application.
Here's my current htaccess code:
RewriteEngine On
RewriteCond $1 !^(index\.php||robots.txt)
RewriteRule ^(.+)$ index.php?/app/$1 [L]

Here's my config code:

$root = "http://".$_SERVER['HTTP_HOST'];
$root .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME\
']);
$config['base_url'] = $root;
$config['index_page'] = "";

$config['uri_protocol'] = "AUTO";

The error I see at http://mysite.com/test/myapp is 404 page not found, but I know the config file is being 'called', as I can see echo'd output from the config file there.


Any hints would be appreciated.

Thanks!
