title: my WordPress 404 Not Found error had been gone :)
body: <p>I used WordPress for the first time and I changed the URL settings and this error appeared </p>
  
  <pre><code>The requested URL /index.php was not found on this server.
  
   Additionally, a 404 Not Found error was encountered while trying to 
   use an ErrorDocument to handle the request.
  </code></pre>
  
  <p>I tried to find <strong>.htaccess</strong> file but there's no such file and I tried to create one but the error still appears </p>
  
  <p>I really don't know what to do .. any help, please?</p>
