Not necessarily 10 years.
We've done many incremental version updates since the first version installed using SMF's web updater from it's control panel.
We've little idea when it broke.
Edit - And just to be clear, It's not a permissions change we did.
We've unchecked/disabled simple search. - Apparently, SMF doesn't remove it from even being seen.
That in and of itself might be one of the bugs with it.
