threads disappear!

[massizero]

Hi, I have a section in my forum where threads disappear.
I don't have any auto delete mod installed.
Is there any area in the admini area where I could have set this option?
thanks

What do you have the view age set to (Forum Manager > Default View Age)?

Under admin control panel, go to Forums & Moderators Block -> Forum Manager -> Edit Forum for Forum in question -> Default View Age

thanks for telling me.. but I don't have this option when editing a forum in the forum manager.
How's that possible?
