Uncaught Error: Class "Monolog\Logger" not found about monolog

[stof]

This error does not make any sense. The Monolog\Logger class exists in Monolog. Make sure you don't have a corrupted vendor/monolog/monolog folder (you can use composer reinstall monolog/monolog)

It occurs a another error too

PHP Fatal error: Declaration of Monolog\Logger::emergency(Stringable|string $message, array $context = []): void must be compatible with PsrExt\Log\LoggerInterface::emergency($message, array $context = []) in /home/mt/vendor/monolog/monolog/src/Monolog/Logger.php on line 681

Do you have the psr PHP extension installed ? If yes, please remove it. This extension is totally broken because it does not account for the fact that all psr/* packages have multiple versions. The working way is to rely on the userland implementation of the PSR interfaces which are managed by composer.
