Sharepoint 2007 to 2010 Upgrade - Visual Problem

Question

I migrated the site from sharepoint 2007 to 2010, also did visual upgrade UIversion to 4. When I view some of lists there is still 2007 visual skin, although the others are shown in 2010 skin. What could be the reason?

Answer 1

The reason is some of the pages are customized so they are unghosted in the database. Try reset to site definition option from Site Settings. You can also build a tool to do it programmatically using these API:
