I've changed all composer requirements versions to dev-master
after composer install and installing flarum via web I got this error:
Fatal error: Cannot use Symfony\Component\Translation\Translator as Translator because the name is already in use in flarum/vendor/flarum/core/src/Locale/LocaleManager.php on line 13
I've fixed this problem with making some changes to LocaleManager.php, but i want make why this problem happening?
I tried both PHP 5.6 and 7.0
