Hi, I just installed the All-in-One Event Calendar on a WP3.3 site. When adding an iCalendar/.ics Feed URL I got this error message.
Fatal error: Ai1ec_Settings::get_instance() [ai1ec-settings.get-instance]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Ai1ec_Settings" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /somedomain/wp-content/plugins/all-in-one-event-calendar/app/model/class-ai1ec-settings.php on line 242
All help would be appreciated, I've no idea where to start. Tnx!
