What does it mean if I get an 'Uncaught Exception: Invalid data provided22 (0)' error?

Notification:

Uncaught Exception: Invalid data provided22 (0) in /path/to/document/root/__swift/library/TemplateEngine/class.SWIFT_TemplateEngine.php:976

Resolution:

When you try to access your helpdesk and you get the above error, then it means your helpdesk is not installed. You need to execute the setup script using the URL http://yourdomain.com/setup/ to install the help desk.
