Thanx, for a quick reply.

You’re right. With CentOS9 comes with a newer version of PHP. The installation went without any problems with CentOS8.

Any news when CentOS9/PHP8 will be supported?

I’m doing a fresh install on a new CentOS 9 just for running FOG.

I came to the part where you need to go to /fog/management to install database schema, but all I get is a http error 500.

In php-fpm/www-error.log is written:
PHP Fatal error: Uncaught TypeError: implode(): Argument #2 ($array) must be of type ?array, string given in /var/www/html/fog/lib/db/databasemanager.class.php:47
Stack trace:

#4 /var/www/html/fog/management/index.php(22): require(‘…’)
#5 {main}
thrown in /var/www/html/fog/lib/db/databasemanager.class.php on line 47

Database is accessible via phpmyadmin without any problems.

Any ideas how to solve this?
