How to overcome error 500 when entering prestashop admin panel?

Question

Prestashop

I'm transferring the site from a local server to nic.ru hosting,
there was a problem when entering the admin panel, the login
form is displayed normally,
but when I try to authenticate, it gives an error 500
, nothing writes to the logs :) I can't figure out where the reason
is, the debug mode is turned on

/* Debug only */
if (!defined('_PS_MODE_DEV_')) {
    define('_PS_MODE_DEV_', true);
}
// добавил еще для принудительного перехода
define('_PS_MODE_DEV_', true);

/* Compatibility warning */
define('_PS_DISPLAY_COMPATIBILITY_WARNING_', true);
if (_PS_MODE_DEV_ === true) {
    @ini_set('display_errors', 'on');
    @error_reporting(E_ALL | E_STRICT);
    define('_PS_DEBUG_SQL_', true);
}

I don't understand anything :(

enable error logging in the hosting settings php module management
Class 'PDO' not found in .....
turned on the PDO module
and everything worked
