what did you actually run? I dont think calling wp-cron.php will actually run cron jobs…
I would deactivate sp and then reactivate… this will restart the cron jobs… and everything should be updated in 1 hour…
but all the stats are updated at once, so if some are updating, they all are… not sure I know which stats you say are not updating – sorry, confused…
Thanks for your answer Mr Papa.
I did run wp-cron.php, which should, according to what I read forces the execution of cron tasks from WP.
I tought it would also affect SP, due to the error I got (located in SP code) when I first ran it.
It’s been one hour and half I have desactivated SP and reactivated it, the numbers hasn’t changed 
About stats, I mean most of the info that are located in the footer:
– moderators name (currently hidden on my forum as the wrong names are shown)
– # of posts and # of members. I believe the other forum stats counts and member stats counts are out of date too, but I have not monitored the numbers yet.
As you say, all the stats are probably affected, so my problem is why aren’t they updated and how to fix it ?
