We are having the same issue.
We are running DNN version: 04.06.00
We have one parent and about 30 child portals.
It seems that every link in every document module, or every forum where documents had been uploaded to posts, have the links breaking.
We have to manually re-attach to the correct document.
At the moment, if you click an un-fixed link, we get the following error: [NullReferenceException: Object reference not set to an instance of an object.]

A simmilar message appears in the Windows Server Application Event log...
Anyone have an idea why this might be happening?
From reports coming in from users, they all seemed to break at once :(
Thanks,
