Subdomain issues. Yii2?

Question

Yii

Good afternoon, the problem is that I created a site on Yii2. And posted it on site.ru hosting. All is well, works great. But I had to move it to the subdomain sub.site.ru As the administrative panel (sub.site.ru/admin) stopped working. And gives an error: Error (#8) An internal server error has occurred. Dedbug panel shows status 500.
What could be the problem? Tell me please. Thank you very much in advance

Answer 1

1. Switch to DEV mode and turn on debug to understand the error in the index file of the web folder

defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'dev');

2. Set up a subdomain in htaccess

Everything turned out to be much easier. It was necessary to configure the template connection from dmstr - adminLTE in the config.
I wrote it like this and everything worked fine:

'components' => [
        'view' => [
            'theme' => [
                'pathMap' => [
                    '@app/views' => '@vendor/dmstr/yii2-adminlte-asset/example-views/yiisoft/yii2-app'
                ],
            ],
        ],
],
