Forum Blank forum due to broken thread for logged-in users only
 

I have a problem that forums suddenly turn blank. This has now happened the second time. I have tried everything that's in the usermanual for dealing with blank pages, which did not help with the issue. The reason for this happening seems to be a broken thread.

The issue also only occurs for logged-in users, and it is cross-browser. Here's the forum currently affected. http://viggo-works.com/vbulletin/for...ews-and-Events

I'd be grateful for any ideas.
