Silverstripe 3.1不会改为dev env

Question

My site is on live online server, after installing few modules (user definded forms) via SSH and Composer i get 500 internal server error. I try to run /dev/build/?flush but nothing is happening. Again the some error!

I check in chrome to inspect in network tab and there is also 500. So dev env in not enabled.

I try to enable it:

_config.php

Config::inst()->update("Director", "environment_type", "dev");

config/config.yml :

Director:
  environment_type: 'dev'

And nothing is happening. It wont to change on dev env to allowe me to run dev/build?flush. I realy dont know what i do wrong.

I also try this way inside _config.php

ini_set('display_errors', 1);
error_reporting(E_ALL);
Director::set_environment_type('dev');
SS_Log::add_writer(new SS_LogFileWriter('./logs/'), SS_Log::WARN, '<=');

This will always put SilverStripe in dev environment.

_config.php

require_once("conf/ConfigureFromEnv.php"); //add this

global $project;
$project = 'mysite';

global $databaseConfig;
//Database configuration

_ss_environment.php

define('SS_ENVIRONMENT_TYPE', 'dev');
error_reporting(E_ALL);
ini_set('display_errors', '1');

define('SS_DATABASE_SERVER', 'localhost');
define('SS_DATABASE_USERNAME', '');// you can leave this empty if you defined this in your _config.php
define('SS_DATABASE_PASSWORD', '');// you can leave this empty if you defined this in your _config.php
