Access denied for user '_DB_USER_'@'localhost'

After making some changes to the settings.php i get this error:

Can’t connect to database, please verify credentials/configuration in settings.ini
Error message: Access denied for user ‘DB_USER’@'localhost’

despite all mysql seetings are there at the settings.php and the settings.ini
When i delete the settings.php i get to the login page but not multiuser, so i have to set up zhe settings.php which lead me to this error

Are ther other places where i have to change this?

Hello @six

The settings file that you need to edit is called settings.ini not settings.php.

Add the following setting under the [interface] section:

enable_multi_user = true
