Bitrix. White screen of death?

Question

1C-Bitrix

Transferred the site on Bitrix to another server.
The assembly of the lamp is all the same,
but Bitrix gives a white page when entering the admin panel, and on the main site:
SetPageProperty$APPLICATION->SetPageProperty("HIDE_CONTAINER", "Y"); ?>
ShowTitle(false) ?>
In /bitrix/php_interface/dbconn.php file: $DBDebug = true; connected
In /bitrix/.settings.php set 'debug' => true
The logs are empty.
What could be?

Answer 1

Understood.
I'll leave it for history and for those who have such garbage pop up:
In php.ini change the value of short_open_tag

Answer 2

Has the PHP version changed? maybe this is the reason

Answer 3

enable logging to the file in /bitrix/.settings.php

'log' => array (
        'settings' => array (
          'file' => $_SERVER["DOCUMENT_ROOT"].'/bitErrorLog.log',
          'log_size' => 3000000,
        ),
      ),
