Problem with space templates

[leoditor]

Hi,

I'm trying to follow AlfrescoTutorial.pdf and create test space via Advanced Space Wizard action. But when clicking on finish i have this error:

   
Error  Please correct the errors below then click Finish.

    * Failed to create new space due to error: The transaction was not committed - Content conversion failed: reader: Content writer: Content

thank you
