well no one eles thought to ask.......

i was only being half sarcastic ive had totaly newbs ask me thos questions about threads dissapering

Yep, people usually overlook the fact that vBulletin at default hides threads over 30 days old in a forum, and that you must switch the value using that drop-down menu on the forum page. I get this question message to me quite a bit on my forum also.

I think you can change the "30 day" thing as default via options. I've just been too lazy to do so.

/me shrugs

Nope - I also get this problem. Always accompanied by an error 1030 "got error 127 from table handler" during a thread update.

If I run check or repair on the thread table it's always fine. All the post records are still there so provided you know the threadid (provided in the error msg) and the forumid (easy to guess - or just pick one and move it later) you can always reconstruct the thread record. I was doing this a couple of times a week with phpMyAdmin but then got bored and wrote a PHP script to automate the process. Takes a threadid and forumid as arguments and reconstructs the thread record.

Still no idea what's causing the problem in the first place though :(
