When i removed the index.php file in the root folder and did dev/build, but getting this error:
---------------
Forbidden

You don't have permission to access / on this server.
---------------

So i put it back, and it is working ok.

I've also tried to add this into _config.php

Director::setBaseURL('/');

It works, but when i click on the navigation to the pages, i get 404 error not found. So i've removed that again.

I've also tried to create .htaccess file in the root site since it doesn't have one, but it still not work, getting this error message:
-------------

My .htaccess file:

    Deny from all

   Order deny,allow

<IfModule mod_rewrite.c>
   SetEnv HTTP_MOD_REWRITE On

   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteRule ^(home|index\.php)/?$ / [L,R=301,NC]
</IfModule>
### SILVERSTRIPE END ### 

I've tried everything from the forums, still no result. Also i've contacted my host server, they don't have the developer to help me out, so i'm feeling a bit annoyed about that!

Anyone be able to help me out on this?? it would be greatly appreciated. :)

Thanks,
Kirsten

try above htaccess, it is normally provided with silverstripe
sometime you have to adjust RewriteBase '/' with root folder like RewriteBase '/dev', then you can remove index.php

hope this help
