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?– UserFeb 6, 2014 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. Feb 6, 2014 at 17:33

I've asked a new question, but it was marked as duplicate of this. Can you give me a hint?– UserFeb 6, 2014 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? May 20, 2014 at 14:32
add_settings_error(
'myUniqueIdentifyer',
esc_attr( 'settings_updated' ),
$message,
$type
);
