• We can no longer get the Simple Calendar plugin to work. Have tried turning off all plugins, reverting back to PHP 7.3, and all other typical debug methods, and nothing has worked.

    This is the error we get on a local install of the site:

    Fatal error: SimpleCalendar\Events\Event_Builder::get_when(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Carbon\Carbon" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide an autoloader to load the class definition in /public/wp-content/plugins/google-calendar-events/includes/events/event-builder.php on line 710

    WordPress: 5.8
    PHP: 7.4
    Simple Calendar: 3.1.36

    Note: We also have the premium add-ons, FullCalendar and Google Calendar Pro, installed on the site; however this issue happens even when they’re turned off.
