Fatal error in Util_Environment

Chnaging the db.php did not work for me, but the steps provided by @martinsdzerve helped, Thanks. Back online now.

Obrigado pela ajuda.

Renomiei o diretório e os arquivos e ao tentar acessar o painel do wp veio essa mensagem.

Atualizar o banco de dados do wordpress

já deu tudo certo

The error “PHP Fatal error: Uncaught ArgumentCountError: Too few arguments to function W3TC\Util_Environment::is_dbcluster(), 0 passed in /var/www/wordpress/wp-content/db.php on line 56” occurs due to insufficient arguments passed to the function “is_dbcluster()” from the W3 Total Cache plugin in the context of a driving school’s website.

To resolve this issue, ensure that you’re passing the required arguments to the “is_dbcluster()” function in the W3 Total Cache plugin. Check the plugin’s documentation or source code to determine the correct arguments and their format. Update your code in “/var/www/wordpress/wp-content/db.php” on line 56 to include the necessary arguments when calling the “is_dbcluster()” function.

@apsixions –

This method completely deactivating this plugin.
To use it again, you should reinstall it.

@moodybuttar – the best way to solve this issue is to upgrade the plugin, because the fix is already implemented.
