I'm using the transition_post_status hook to perform some operations after publishing a post. In some conditions I would like to show an error message in a red box under "Edit Post" and above "Post published":
How can I do that?

I wouldn't use that hook. Here's why
Try something like this using admin_notices.
function wpsites_admin_notice() {
$screen = get_current_screen();
if( 'post' == $screen->post_type
&& 'edit' == $screen->base ){
?>
<div class="error">
<p><?php _e( 'Updated Demo Message!', 'wpsites' ); ?></p>
</div>
<?php
}}
add_action( 'admin_notices', 'wpsites_admin_notice' );
Untested.

Great! But how can I figure out in the
wpsites_admin_noticefunction what is the error that has occurred? – User Feb 6 '14 at 17:31 -
This simply shows you how to display the message. To work out any errors is another question which you should ask or change your original question. – Brad Dalton Feb 6 '14 at 17:33

I've asked a new question, but it was marked as duplicate of this. Can you give me a hint? – User Feb 6 '14 at 20:09

You could change debug from FALSE to TRUE in your wp-config.php but not sure what errors you are trying to troubleshoot? – Brad Dalton May 20 '14 at 14:32

add_settings_error(
'myUniqueIdentifyer',
esc_attr( 'settings_updated' ),
$message,
$type
);
