This can’t be right, it’s insane. What’s insane ? Well it appears that the LastContentModifiedDate gets updated when the Site Usage is re-calculated. So my Last Modified webpart is made pretty much useless by having the SiteUsage data enabled.
That blows. Hope its just coincidence.
I know this was 4 years ago but did you clear LastContentModifiedDate as useful or trash it as useless?
Gave up on it as a bad job
