 * The plugin does what is needed, but breaks pages if debug is set to true.
 * PHP Notice: Undefined variable: comment_tag in wp-content\plugins\last-updated-
   shortcode\last-updated-shortcode.php on line 59.
 * A similar post with a solution was posted 4 years ago, but was never acknowledged
   by the plugin author and does not work now.

 * The suggestion to fix the above undefined variable notice was not clear to me,
   when I tried to apply it and it did not work. I then realised what was intended.
 * For it work, you should insert the line `global $comment_tag;` in the empty line
   58 (i.e. before present line 59 to stop the notice from appearing.
