I'm not sure if it is the version from the trunk that I'm installing but everytime I try to install Website Builder Module it gives me this error:
TypeError: The model "website.qweb.field.qweb" specifies an unexisting parent class "ir.qweb.field.qweb" You may need to add a dependency on the parent class' module.
Any ideas, i did some debug on the code but with no luck
