A group of Microsoft Products and technologies used for sharing and managing content, knowledge, and applications.
According to many threads posted here, this is a common problem which Msft has been unable to explain. I also posted about several "phantom" features that wouldn't activate on the assumption that Msft would identify them and resolve the issue, but they never did. Based on the poor development practices applied to sharepoint and its many unresolved bugs, the only conclusion we can reach is that site templates don't work properly so I wouldn't invest too much time in them.
