The code-
$sql = 'INSERT INTO kiosk_registration ( kiosk_name, mini_info, grade, domain, phonenumber, password, referrer_id, kiosk_id, user_id)
VALUES ("'.$_POST["name"].'", "'.$_POST["mini_info"].'", "'.$_POST["grade"].'", "'.$_POST["domain"].'", "'.$_POST["phone_number"].'", "'.$_POST["password"].'", "'.$_POST["ref_id"].'", "'.$kiosk_id.'", "'.$_SESSION['uid'].'")';
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}

The error - Unknown column 'password' in 'field list'. And this started happening on its own. It used to work perfectly fine, but this error just started appearing suddenly. I have no clue as to what could be wrong.

* Sorry guys, it was a small problem, i mixed up the files, I was updating and not inserting hence the error *
