TFS 2012 web interface error: Unexpected end of file while parsing Name has occurred. Line 1, position 4001.

After modifying our work areas I encountered the following error when trying to access backlog, board, or work items:

TF400917: The current configuration is not valid for this feature. This feature cannot be used until you correct the configuration.

Now, when I attempt to modify anything in areas, I encounter the following error:

Unexpected end of file while parsing Name has occurred. Line 1, position 4001.

When I attempt to add a new work item, I encounter the following error: 

• Unexpected end of file while parsing Name has occurred. Line 1, position 4001.

  Error: Unexpected end of file while parsing Name has occurred. Line 1, position 4001.
