title: TYPO3 Cannot Access to Installtool after upgrade from 9 to 10
body: <p>i've updated from Version 9.5 to 10.4 and after that i cant acces the Installtool anymore.</p>
  <p>It stucks at &quot;Checking session and executing silent configuration update&quot;...</p>
  <p>All i want is to repair the Database! Is there any other way to do this?</p>
  <p>The Console log shows me &quot;GET <a href="https://mywebsite.net/typo3/install.php?install%5Bcontroller%5D=layout&amp;install%5Baction%5D=executeSilentConfigurationUpdate" rel="nofollow noreferrer">https://mywebsite.net/typo3/install.php?install[controller]=layout&amp;install[action]=executeSilentConfigurationUpdate</a> 200 OK&quot; over and over again (canceled at 4000 trys..)</p>
  <p>Any idea?</p>
