pertama buka folder yang ada di adminweb lalu cek_login buka dengan notapad ++ dll x
 cari ini
$username = antiinjection($_POST[username]);
$pass     = antiinjection(md5($_POST[password]));

dan ubah dengan penambahan tanda petik

$username = antiinjection($_POST['username']);
$pass     = antiinjection(md5($_POST['password']));

dan untuk

hapus  session_registerx
session_register("namauser");
session_register("namalengkap");
session_register("passuser");
session_register("leveluser"); 
menjadi
("namauser");
("namalengkap");
 ("passuser");
 ("leveluser");



semoga bermanfaat :)
