Ben bir JPEG görüntüsü yüklediğinizde, hata "Göndermeye çalıştığınız dosyaya izin verilmemektedir." Gösterir. Ne benim koduyla yanlış?

Ana HTML kodu:

<form action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="userfile" id="file"/>
    <button>upload</button>
