Maybe your forum was being ddos'd but go to your AdminCP -> Maintenance -> Update Counters -> Update Statistics.

Do you mean -Rebuild Statistics-
This comes with a warning-
Rebuilding statistics will cause the loss of the total forum view and active users data. Only run this if you believe you really need to! Once the data has been replaced, there is no way to restore your database.

Is this safe to run?
