Can we see the code to store the password in database? If you use normal form of the password when you inserting it to DB, I guess problem should be here, 

$_POST['pass'] = md5($_POST['pass']);
        
        //gives error if the password is wrong
        if ($_POST['pass'] != $info['u_pass']) {
            die('Incorrect password, please try again.');
            //this gets executed when supply correct password.
        }
