Добрый день всем!
Подскажите пожалуйста, в чем может быть дело. Имеем инсталятор Drupal версии 6.2. Запускаю "/drupal/install.php", получаю html-страницу с такими ошибками:

Warning: array_keys() [function.array-keys]: The first argument should be an array in C:\web\apache\htdocs\drupal\includes\theme.maintenance.inc on line 217
