    When a user Is not logged in and leaves a comment, I get these errors:

    Notice: Trying to get property of non-object in C:\xampp\htdocs\scanwp-blog\wp-content\plugins\crayon-syntax-highlighter\crayon_wp.class.php on line 717

    However, when logged in everything is fine.
    How can I fix this?
    Thanks!

  • For the Cannot modify header information – headers already sent warning, commenting out lines 218 and 220 (in version 2.8.4) seems to solve it:

    if ($output_text) {
    //header('Content-Type: text/plain');
} else {
    //header('Content-Type: text/html');
}
