I'm working with a new site collection in SharePoint Server 2010 Standard created using the Blank Site template. I would like to add a Content Query Web Part to one of my web part pages, however, this web part does not show up any of the web part category lists. I have already gone into Site Collection Administration → Site Collection Features and activated the Search Server Web Parts, but the CQWP still doesn't show up. Am I missing something?
The Publishing Features need to be active on the site collection for the web part to appear. It can be activated from the Site Settings, Site collection features screen.
