problems with urls

[eluser]walrus86[/eluser]
hi, i'm still trying to solve this problem, and I think that maybe I found the problem.

I found a tutorial in
http://www.davidrojas.net/index.php/desa...deigniter/

At the begining of the video, the guy just changes: $config['index_page'] = "index.php";
into: $config['index_page'] = "";
in the file config.php

and then he creates the htaccess file with the code:

Code:

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /system/index.php/$1 [L]

I see there's a "robots.txt" in the second line. So, is it posible that the error I get is because i don't have any robots.txt file???

thanks again for taking the time to read
