title: TYPO3 9.5.21 startpage /index/ in URI
body: <p>I've updated TYPO3 from 8.x to 9.5.21 and the page is available like this <code>http://example.com</code></p>
  <p>But if I go back to the startpage it always appends <code>/index/</code> and then the URI looks like this <code>http://example.com/index/</code>.</p>
  <p>Does anybody know what the problem is?</p>
