problems with statestic

I can see that around 1000 did visit my spip site ( 2.09) yesterday…
But I can not see the details ( exec=statistiques_referers&jour=veille )

Also I can see that zero did visit the same site today…
I guess that the statistic module is a bit corrupted…
Anybody know how to reset it, and make it start counting again?

Might be one of the plugs that need to be removed…
Did use ( but it did not work ) visiteurs_connectes

And yesterday i installed the ispip plug…

are they incompatible…

the installed plugs now are:

cfg: moteur de configuration
Compositions
iSPIP 1.0 - Squelette optimisé pour l’iPhone / iPod Touch basé sur iUI
Liens spip_out ouvrants
Social tags
SPIP Bonux 2.0
SPIP-Listes
Thickbox v2

PS
did install ispip yesterday… could b the problem…
do statestic need any write rights eg chmod 777 etc…?
