The farm was upgraded from MOSS 2007 to SP 2010. There are a small number of sites that contain lists and libraries which are no longer accessible. I would like to delete these, but when I open the site in SP Designer 2010, it does not display any of the lists or libraries - good or bad. There is a left column entry called lists and libraries, but when I click on it, it says there are no items to show in this view. There are lists and libraries that work just fine.
I have full control on the site. I have also tried using sharepoint admin accounts. SPD 2010 brings up the site. If I go into Site Settings > Site Lists and Libraries, the list and library that I want to delete are listed there for customization, but selecting either of them results in an error message.
Is there a way, perhaps via PowerShell, that I could delete the list and library that are giving me problems?
