How can I fix following when i got error try to upgrate as Ver. 1?

Question

I got error as following:

qa-app-users.php on line 181
/qa-app-users.php on line 192
/qa-index.php on line 528

Answer 1

All of these lines are trying to set HTTP headers. I cannot be sure unless you show the error in full, but I suspect this is because something has already been output to the browser by the time these lines are reached, so the HTTP headers can no longer be set.

I don't think this is a problem in the release itself, so perhaps you modified a file, maybe accidentally. It can be as simple as a blank line outside of <?php ?> tags, creating by a mistaken press of the return key on your keyboard.

If you view the error in full, it should tell you exactly where this output happened - in which file, and in which line, so you can check there.

when i edit to qa_base.php for replaced some funtions I got error as above.
 I replaced as

  function qa_q_request($postid, $title)
    {
        return (int)$postid;
    }

---

I got it and it is happened because of you changed $postid to $questionid.

Thank.
