Hindrik on "[Plugin: iThemes Security (formerly Better WP Security)] 403 Forbidden | New Wordpress site"

Hi,

I would like to upload a new wordpress site to my host. But every time I try I'll get the following error:

Forbidden You don't have permission to access /wp-admin/install.php on this server

I think it has something to do with the security plugin i'm using on my main website. I tried deleting everything except for the following from .htacces:

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

But that didn't work either.
Tried 777 on the folders but no results.

Can you guys help me out?
