If you create and publish a private or protected post, the title will be amended with this status. Adding the below code to the functions.php file will remove the title alteration and make things look that little bit nicer.
function the_title_trim($title) { $title = attribute_escape($title); $findthese = array( '#Protected:#', '#Private:#' ); $replacewith = array( '', // What to replace "Protected:" with '' // What to replace "Private:" with ); $title = preg_replace($findthese, $replacewith, $title); return $title; } add_filter('the_title', 'the_title_trim');
