Hi all,

I'm having a problem installing the workflow module. I've managed to install a couple of other modules without any problems, but when I extract the Workflow module (v1.0RC3) into the root of my site and rebuild the database, I get the following error:

Warning:  Unknown class passed as parameter in C:\wamp\www\iq\sapphire\core\Object.php on line 445
Fatal error:  Uncaught exception 'ReflectionException' with message 'Class SiteConfig does not exist' in C:\wamp\www\iq\sapphire\core\Object.php:273

I'm totally new to SilverStripe so I'm not too sure what's going on. I'm running SilverStripe 2.3.7. Am I missing some config option somewhere or something?

The Workflow Module is apparently only compatible with with SilverStripe 2.4, according to this post:
http://www.silverstripe.org/all-other-modules/show/277481

Looking at the Workflow Module page, it doesn't look like there was ever a version that was compatible with SilverStripe 2.3.

You are correct. Workflow is a new module and has only ever been released / developed for 2.4.
