I’d made an error when checking the author field input. * Please open wp-bulletin-board/php/wpbb-edit-topic.php around line 295 and find: * ``` if (isset($_POST['wpbbpostauthor'])) { if (is_numeric($_POST['wpbbpostauthor'])) { // Strip all tags from the authors name $post_author_name = wp_strip_all_tags($_POST['wpbbpostauthor']); // Retrieve ID back from username $post_author = wpbb_parse_author_name(NULL, $post_author_name); } else { $post_author = absnt($_POST['wpbbpostauthor']); } } ``` * **Replace with:** * ``` if (isset($_POST['wpbbpostauthor'])) { if (is_numeric($_POST['wpbbpostauthor'])) { $post_author = absint($_POST['wpbbpostauthor']); } else { $post_author_name = wp_strip_all_tags($_POST['wpbbpostauthor']); $post_author = wpbb_parse_author_name(NULL, $post_author_name); } } ``` * Thanks for letting me know.

If a user edits a post the author becomes guest.”” * Do we have to change something else?
