 * I’m getting this message above the favorite button, as well as above the list
   on my sidebar displaying all my favorite posts (the message appears for each 
   favorited post, so it can be multiple – dozens – of times, depending on the user):
 * > Warning: in_array() expects parameter 2 to be array, null given in /home/…/
   > public_html/wp-content/plugins/favorites/app/Entities/User/UserRepository.php
   > on line 188
 * The button works just fine, but these messages won’t go away.
    What’s the matter
   and how to fix this? Thank you.

 * No response from developer, but thanks to Aristeides Stathopoulos in GitHub, 
   replacing define(‘WP_DEBUG’, false); in WP-config file does the trick…
 * ini_set(‘display_errors’,’Off’);
    ini_set(‘error_reporting’, E_ALL ); define(‘
   WP_DEBUG’, false); define(‘WP_DEBUG_DISPLAY’, false);
