I have created a full site starting from a Joom51 demo pack (with a mix of Calibra and Cashmere) on it.
This config info says it runs on a Joomla 3.3.6 engine.
Question: does the demo packs include the "full standard" Joomla functionality ?
I ask this because Versioning of articles does not work (it says "404 - component not found"

Btw: debugging mode with full dev info does not bring more details about the problem.
Any idea ?
Thanks in advance,
