Did the error disappear? It should NOT show if they're following all recommendations, there are 3 checks for suhosin); a new warning should display a link to the suhosin page that was added, what data shows on the page? Could you take a screen shot of the page for me (I need to be sure all checks populate properly).
If the page does not show that means that the suhosin check found no problems, could you go to the page manually by going to: admin/suhosin.php
For users experiencing that the suhosin check does not turn off when you're within parameters, please see my posting at UBBDev
