I am using the May 11th release version and when I try to view an individual forum post (accessing thread.aspx) I get the following error:

Any ideas what the problem could be? This is the second time I have launched a website with this starter kit and the first time I had no trouble at all with the forums.

Thanks in advance.

Quick update - After additional testing I realized that the problem was that the original posts in the thread were made by a user that had been subsequently deleted.

New threads from current users seem to work fine.

While my particular problem is solved, it seems like there can certainly be issues down the road in the life of a forum if threads no longer become visible because a person who posted to it has been deleted.

Yea... I knew about that issue. I need to 1) figure out if that still applies and 2) make a fix.

I figured it was a known issue. Thanks for all of the great work, I am putting the sites to good use. I look forward to version 3 and hope there is an upgrade path from v2 to v3. Thanks again.

I'm experiencing this same problem - a deleted users forums are no longer accessible. Is there a fix to this problem?
