php - newscoopインストールエラー

Question

Newscoop 4 Scriptを自分のWebサイトにインストールしようとすると、次のエラーが発生します。

Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /home/content/24/8222924/html/newscoop4/application.php on line 65

Parse error: syntax error, unexpected T_FUNCTION in /home/content/24/8222924/html/newscoop4/application.php on line 68

エラーが表示されるファイルはこれです。phpでは完全にレンダリングできないため、バックスラッシュと関係があると思いますが、私のphpバージョンは5.3です。
