Issue: when we upgrade any site from SharePoint 2010 to SharePoint 2013 and that site contains custom site definitions, we face the issue.

Solution: Ensure to follow the steps below to resolve the issue.

1.   Both versions of the site definitions (14 and 15) need to be present  in respective hives at the time of performing upgrade. If either of them is not there then the above error will show up.

2.   Uninstall > Remove  and  Add > Install. This had removed the previous site definition files (one and template folder) from 14 hive and added latest files to 15 hive.
