I changed the pw for my MYSQL database user (in retrospect I shouldn't have done that), but when I wanted to edit my database settings in _config.php to my surprise there was no $databaseConfig defined in the file. Have no _environment file so I'm wondering where I can find these settings.

Have inherited this site from someone else so I'm not a Silverstripe expert. Any help would be appreciated.
Using SS 2.3.1

Lennert

Went into dev mode and got the following error:

=======

(Changed pw). So it looks as if it's getting the correct info.
Will continue digging.
