I created a site with the JA VITAL tempate a month ago, however I wanted to try something else, so I put this under a subfolder, then I installed the quick start of the Uber template for Joomla 4, at the end of the installation I enter the configuration iforms in the site installation process, everything is fine, when it is finished when I click on the "access the administrator" button, I got fatal error, can you help me please

Hi ludo974,
I have fixed the site and it was working well.
Locate the file administrator/cache/autoload_psr4.php and delete it. Access Joomla 4 again and the file will get recreated automatically. This file is a map of all PHP classes Joomla uses and it is created and maintained automatically.
