I had Silverstripe 2.4.4 installed on Godaddy, originally. And had Dataobject Manager and Event Calendar working great. When we went to migrate it over from the development site, to the production, which is on Network Solutions, it was easy peasy and everything worked great; except the Event Calendar.
I'm now getting this error:
Fatal error: Argument 1 passed to LiveCalendarWidget::__construct() must be an instance of Calendar, called in [full path from root]/httpdocs/event_calendar/code/Calendar.php on line 877 and defined in [full path from root]/httpdocs/event_calendar/code/CalendarUI.class.php on line 89
Any ideas? I'm absolutely stuck...
