Installed Magento on Apache 2.4.2 / PHP 5.4.4 After installation frontend works okay. When going to backend /backend i get login screen, but after i entered my credentials i go to 404 (whoops, our bad) with url (example) http://localhost/magento2/index.php/backend/admin/dashboard/index/key/877719217bb8c880dc4e67538d998631/
