title: TYPO3 Upgrade ( 7.6 to 10): Site Configuration not found
body: <p>I have been spending the day trying to upgrade my TYPO3 installation from version 7.6 to 10.4 and with some struggles in between everything went fine, to the point that I can login into the backend and so on and so forth.</p>
  
  <p>The problem that I am facing for some hours now is that I can't get the front-end to work.</p>
  
  <p>I get the following error:</p>
  
  <blockquote>
    <p>Page not found.
    The page did not exist or was inaccessible. Reason: <strong>No site configuration found</strong></p>
  </blockquote>
  
  <p>I have been scrolling for google for quite a bit now and I can't seem to find the right solution right now.</p>
  
  <p>The way I went was to install T3-10 with composer and migrate the DB and run the upgrade wizard. I also checked for the "site configuration" within the backend and also the site configuration part in the filesystem and everything seems to be ok.</p>

  <p>I am sure it's just something little that I can't seem to find right now, anyone else experience with this?</p>
