 * Getting the following error
 * Error message: Cannot redeclare twig_array_batch() (previously declared in /wp-
   content/plugins/all-in-one-event-calendar/vendor/twig/Extension/Core.php:1399).
 * Was advised the All-In-One Event calendar is using an outdated version of a library
   called Twig.
 * Before I investigate another calendar plugin, am wondering if a fix for this 
   is in the works.
 * WordPress version 5.6
    PHP version 7.3.26
 * Thank you.
