One of our customers has created a My Site area (with default settings), and then created a new site 'TestSite' in their content area. When they try to create a new site in another My Site area (on the SAME sharepoint instance) using this template, the site cannot be created due to a site collection feature not being activated. Some research online shows the error guid corresponds to 'My Sites Blog'.
I think I know how to activate that feature using the powertools, but I don't understand why this feature, if enabled in one My Site appears to be missing when used in a different My Site on the same server.
Kinda feels like you shouldn't create a site template from a site in a My Site area, or perhaps this is a bug.
Anyone have any insight here?
