I have the same error:
Warning: array_key_exists() expects parameter 2 to be array, null given in /data/web/virtuals/249174/virtual/www/domains/vinarium-brno.cz/wp-content/plugins/restaurant-reservations/includes/MailChimp.class.php on line 75

How can I fix it?
The theme is switched to “block” view. How can I switch the one to normal theme?
Thanks, but all these elements are switched to Show.
