I’ve added /agriturismo/%postname%.html as Rewrite Slug but it doesn’t work.

Yes, I called it. This is the code:

add_action('admin_menu', 'gp_call_add_rewrite_page');

function gp_call_add_rewrite_page() {
    add_menu_page('Rewrite Page', 'Rewrite Page', 'manage_options', __FILE__, 'gp_add_rewrite_page', 'dashicons-edit');
}

function gp_add_rewrite_page() {
    ?>
    <div class="wrap">
        <h2>Rewrite Page</h2>
        <?php
        global $wp_rewrite;
        var_dump($wp_rewrite);
        ?>
    </div>
    <?php
}

I set permalinks to /%postname%.html in Settings > Permalinks

It works! Many thanks.

I better explain. I’ve integrated osCommerce and WordPress so I have in the same directory both osCommerce installation and wordpress installation. I renamed index.php to blog.php to not override index.php file of osComemrce installation.
See here.

I renamed it because in the same directory I have already a file called index.php

If I move the index.php file OK, but if I rename index.php to blog.php doesn’t work right because blog.php become a directory so wordpress search for blog.php/index.php file. In fact when I try to rebuild permalink wordpress search for htaccess file in the directory called blog.php/.
