Hi, I have a client who is using Easy Appointment and they are getting the following error.   Warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'EAC_Woo_Logic' does not have a method 'checkout_item_event' in /wordpress/core/5.5.1/wp-includes/class-wp-hook.php on line 287 It looks like it is related to Easy Appoint Connect.   Any help would be appreciated.   Thank you!
