jquery-file-uploadの基本的な動作について

皆様初めまして

私は現在以下のものを利用してphpでファイルのアップロードを実装しております。
jquery-file-upload

vangrant+virtualHostの環境でドキュメントルート配下に「test」フォルダを作成し、その中に上記リンクよりダウンロードしたフォルダをそのまま格納して動かそうとしたところ、開発者ツールにて「http://127.0.0.1:10080/test/server/php/ 500 (Internal Server Error)」
と怒られてしまいました。。。
権限の問題かなと思い、設定ファイルで指定されているアップロード先「server/php」に権限を「777」としてみましたが、結果は変わりませんでした。
こちらを動かす際になにか足りない設定などは御座いますでしょうか？
