提交多个段落时出现403错误

Question

I have a problem with a comment box input.

Everything works very well when only one paragraph is sent, but when multiple

tags are added, i recieve a 403 error. This doesn't happen on the localhost, only on the live website. The textarea is a rich-text editor using CKeditor. I use the same setup on another page where it does work. Can you please help me?

This is the form:

<div id="comment-form" class="container">
    <h3>Laat je mening horen!</h3>
    <form class="form-horizontal" role="form" method="POST" action="blog-item.php?blogID='.$blogID.'">
        <div class="form-group">
            <div class="col-sm-6">
                <input type="text" name="auteur" class="form-control" value="'.$_SESSION['username'].'" disabled>
            </div>
        </div>
        <div class="form-group">
             <div class="container col-sm-10">
                 <textarea rows="8" class="form-control" placeholder="Schrijf hier je commentaar" name="commbox" id="commbox"></textarea>
             </div>
        </div>
        <button type="submit" class="btn btn-primary btn-lg">Verstuur</button>
    </form>
</div>

and this is the php that processes the input:

if ($_SERVER["REQUEST_METHOD"] == "POST"){
    if(empty($_POST["commbox"])){
        echo '<p class="alert alert-danger">Je kan geen leeg comment versturen</p>';
    } else {
        $commbox = htmlspecialchars($_POST['commbox']);
        $auteur = $_SESSION['username'];
        $addCommStmt = $mysqli->prepare("INSERT INTO blogcomments (blogID, comment, auteur) VALUES (?, ?, ?)");
        $addCommStmt->bind_param('sss', $blogID, $commbox, $auteur);
        $addCommStmt->execute();
        $addCommStmt->close();
    }
}

它可能与您的代码无关。它更可能与服务器上的mod_security有关。为了进行测试，请更改尝试提交的整个文本，如果一切正常，则需要请求主机支持将某些mod_security列入白名单。劳斯莱斯。
