Lost posts, can't restore

My forum is http://allaboutbigbrother.forumotion.com/index.htm
Obviously something is going on today. Even the support forum is acting funny.

Certain users posts are gone, the bottom of the forum does not show who is online.
It seems that I as the admin am the only one who can post.

I was trying to restore my forum, but the utility won't accept my information.

Can someone help? Thank you!

Update.. was able to use restore utility, but it did not fix my problem.
I have lost a lot of functions of my forum

The same happen to me today lost of posts in security shows forum automatic prune...???
Utilities and restoring don't help and as i know isn't good to use restore forum at list once in 24 hours maybe i am wrong?
I have stoped moderators to delet posts they only can edit them
