Question

Prestashop

I downloaded the latest version of CMS PrestaShop 1.6.1.0 from the official site, unpacked the contents of the archive, into the OpenServer -> ../domains/sitename folder, opened the browser, started the installation, and at the last moment at 72%, the PrestaShop installation terminated with an error message.
Here it is:

Here are the OpenServer settings:
What I tried to do:
Re-downloaded the PestaShop archive and unpacked it into the desired OpenServer folder;
Changed OpenServer settings (versions of PHP, MySQL, Apache);
A trace appears in the PHP logs. line:
[10-Jul-2015 18:19:28 Europe/Moscow] PHP Warning: array_key_exists() expects parameter 2 to be array, null given in D:\OpenServer\domains\sitename\classes\Language.php on line 610
In the Language.php file, line 610 contains the following:

public static function getLanguage($id_lang)
  {
    if (!array_key_exists((int)$id_lang, self::$_LANGUAGES)) // 610 строка
      return false;
    return self::$_LANGUAGES[(int)($id_lang)];
  }
