title: Sitemap generator finds only one page
body: <p>I've tried to generate an <em>XML</em> sitemap from different sites (<a href="https://www.xml-sitemaps.com/" rel="nofollow noreferrer">XML-sitemaps</a>, <a href="https://www.seoutility.com/tools/google-sitemap-generator/" rel="nofollow noreferrer">Seoutility</a>, <a href="https://toolset.mrwebmaster.it/seo/sitemap-generator.html" rel="nofollow noreferrer">MrWebMaster</a>) but they all create a one-page sitemap.</p>
  
  <p>In other words, they can't find subdirectories into my website.</p>
  
  <p>I've tried all <code>www.mydomain.online</code>, <code>mydomain.online</code>, <code>https://mydomain.online</code>, and <code>https://www.mydomain.online</code> <em>URLs</em>, but nothing changed.</p>
  
  <p>I didn't implement <em>URL rewriting</em>, so my website structure is:</p>
  
  <pre><code>folder
  |-----index.php
  |-----something.inc.php
  |-----subfolder1
        |-----index.php
        |-----somethingelse.inc.hp
  |subfolder2
        |-----index.php
        |-----foo.inc.php
        |-----bar.inc.php
        |-----subfolder4
              |-----index.php
              |-----baz.inc.php
  |subfolder3
        |-----index.php
  </code></pre>
  
  <p>and so on...</p>
  
  <p>The problem is that even <em>Gooogle Search Console</em> indexing system does only find one page into my website (and that's why I decided to build a sitemap).</p>
  
  <p><em>Do I have to change something in my configuration or tell it to the generators in some ways to make them work?</em></p>
