You can edit WordPress post label to something Else. For example if you want to edit Posts (label) to Article so that anytime you or any other member visit you wp-admin (dashboard) he can see Article as a label on sidebar menu not posts (which is by default).
For doing this, open your theme’s function.php file and add the following code:
add_filter(‘gettext’, ‘change_post_to_article’);
add_filter(‘ngettext’, ‘change_post_to_article’);
function change_post_to_article($translated) {
$translated = str_ireplace(‘Post’, ‘Article’, $translated);
return $translated;
}
