Upgraded from 6.0b4, and noticed the following things after I ran all the install stuff in order.

1. When displaying a thread I get "B_ParentUser" not a column in _Posts. I checked the table, and there is no B_ParentUser column.... and none of the alter scripts seem to create it!

2. In the private messages section, each user of existing private messages sent is listed as "Deleted User". The entire M_Sender column in the messages table = 1. Something went cuckoo.

3. We get "the form you have submitted is no longer valid" on each and every attempt to post a message.

Can anyone fathom what may have gone wrong in our upgrade?

Thanks
