       [06-Dec-2022 10:27:55 UTC] PHP Notice:  Undefined index: type in /var/www/html/wp-content/plugins/semantic-linkbacks/includes/class-linkbacks-mf2-handler.php on line 454
       [06-Dec-2022 10:27:55 UTC] PHP Warning:  in_array() expects parameter 2 to be array, string given in /var/www/html/wp-content/plugins/semantic-linkbacks/includes/class-linkbacks-mf2-handler.php on line 305
       ```
   
 * perhaps the undefined indexed (line 454) could be remedied by first checking 
   isset($meta[‘type’]) ?
 * on line 305 should instead check if $commentdata[‘target’] == $properties[‘category’]?
 * Thanks!
