Code:

///////////////////////////////////////////////////////// Action: POST

if ($action == "post") {

        $forumid = $_POST["forumid"];

        $topicid = $_POST["topicid"];

        if (!is_valid_id($forumid) && !is_valid_id($topicid))

                die("w00t");

        $newtopic = $forumid > 0;

        $subject = $_POST["subject"];

        mysql_query("INSERT INTO ajshoutbox (uid, date, name, text) VALUES(0,NOW(),'Auto Message Forum', 'Un nouveau message dans le forum par " .$CURUSER['username']. "  ...Voir " .$subjectp. "Le Message')") or sqlerr(__FILE__,__LINE__);

        if ($newtopic) {

                if (!$subject)

                        showerror("Erreur", "Vous devez entrer un sujet.");

                $subject = trim($subject);

                //if (!$subject)

                        //showerror("Erreur", "Vous devez entrer un sujet.");

                //showerror("Erreur", "Sous réserve est limitée à $maxsubjectlength caractères.");

        }else{

          $forumid = get_topic_forum($topicid) or die("Bad topic ID");

        }

is showing that error
