I installed event_calendar module with no problems. The dev/build runs fine in SilverStripe-2.3.6. i can see the new pagetypes and add and configure event_calendar/events in the CMS. So far - so good. But when i call the URLs i only get completely empty pages - no error - no page - just empty. Regardless wheter in live or development mode. In php-log I have: [05-Mar-2010 14:42:45] PHP Fatal error: Class 'UpgradeSiteTreePermissionSchemaTask' not found in /opt/silverstripe-2.3.6-1/sapphire/core/model/SiteTree.php on line 968

Any Idea?
