...no components are out of date. What I'm trying to determine is which components the SEPM believes is out of date.
Just to help clarify, the screenie I posted shows the date and revision of the current latest definitions for SONAR, but my SEPM identified them as out of date. In my case, it was down to the date format issue as linked by Rafeeq, but I resolved my issue by changing the date separator to the minus - sign instead of the forward slash. As the article says, you gotta leave it for a little while after making the change, in order for it to take effect.
Sooooo, on the home page, and when you click on the "Out-of-date" link next to the pie-chart, which components does the SEPM incorrectly think are out of date? If this is where you checked earlier, are you able to provide a screenie too please?
