Today one of our SharePoint guys messaged me over Lync with a need to setup social web parts in SharePoint. What he noticed was that he was looking for the note board, organization browser, tag cloud , etc. It seems that somewhere in the past this feature was lost. Possibly during the SharePoint upgrade from 2007 to 2010.
To sum this up a bit. After a database attach upgrade of a site collection/content database from SharePoint 2007 to 2010, some of the web parts that you might expect to become available were not.
To fix this we used powershell and did the following:
Disable-SPFeature –Identity PortalLayouts –url http://corp.sharepoint.local
Enable-SPFeature PortalLayouts -Url http://corp.sharepoint.local
The issued was resolved
