If the config.php isn't there, I'm pretty sure you can create it. You only have to paste this in there:
<?php return array (
'debug' => false,
'database' =>
array (
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'XXXXX',
'username' => 'XXXXXX',
'password' => 'XXXXXX',
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => false,
),
'url' => 'XXXXXXXXX' . getenv('VIRTUAL_HOST'),
'paths' =>
array (
'api' => 'api',
'admin' => 'admin',
),
);
You"ll have to change database, username, password and url. If you want to enable debug mode, set "debug => false," to "debug => true,"
Correct me if I'm wrong, guys.
