Không biết bạn dùng skin nào, nếu bạn dùng skin giống ITVNN thì tìm vào thay lại toàn bộ đoạn code sau:
<!-- login form -->
<form action="login.php?do=login" method="post" onsubmit="md5hash(vb_login_password, vb_login_md5password, vb_login_md5password_utf, 0)">

textbox.style.color='#828282';
}
}
</script>
<!-- / login form -->Còn nếu là skin khác thì bạn nghiên cứu đoạn code trên sửa lại cho phù hợp hoặc bỏ luôn chữ Ký danh trong ổ đăng nhập bằng cách tìm trong template header đoạn code sau:
value="<vb:if condition="$username">{vb:raw username}<vb:else />{vb:rawphrase username}</vb:if>"Thay thế bằng:
value="<vb:if condition="$username">{vb:raw username}<vb:else /></vb:if>"
