when i run the following cmd

composer create-project roadiz/standard-edition;

I keep getting the following error:

[31-Mar-2018 21:29:52 Europe/Paris] PHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [1045] Access denied for user ''@'localhost' (using password: NO)' in /home/cpaneluser/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:43

is there any solution to this?

Since i assigned the db info inside .env but now i got this error

Update: after putting it all back as it is, now it does not generate any error_log but website is still showing up blank???

i'm also installing this on shared host with cpanel, i remember getting this cms working fine on this like 2 years ago. But now it just wont work anymore.
