title: SSRS Report suddenly not working
body: <p>I have a web portal that calls up reports on my report server.  One report in particular suddenly stopped working this morning from the portal.  I can look at it in Visual Studio and in the Report Manager, but it doesn't work when viewed through the portal.  When I look at the log to see what happened, I see this: </p>
  
  <pre><code>The operation you are attempting on item '/' is not allowed for this item type
  </code></pre>
  
  <p>I have made no changes to this report in weeks, so I have no idea what happened, what this error means, or what I can do to fix it.</p>
