Page permalinks & Internal server error 500

Hello,
I’d like to set permalinks for my site.
In the control panel I set custom permalink like this:
https://www.mysite.com/%page%

I put an empty .htaccess file with write permission.
Wordpress write in it this:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

In my httpd.conf file I wrote:
<Directory/>
Options FollowSymLinks
AllowOverride All
</Directory>

I have the mod_rewrite module installed.

Everything seems ok but when a copy my file .htaccess in my root folder and I set the custom permalink in the control panel NOTHING in my site works.
I have an Internal Server Error (500)

Any suggestions
