Problème statistiques

Bonjour
Depuis quelques jours, les statistiques n’affichent aucune visite et j’ai le message suivant:

Warning: actualiser_sessions(../tmp/sessions/1_16f49b6fd71ecd2628bddcf2d02447a5.php.7618733934fa0f2e8e65164.13645636.15657664304fa0f7984e2ff9.26198225) [function.actualiser-sessions]: failed to open stream: No such file or directory in /mnt/132/sdc/9/a/countrymilly/ecrire/inc/session.php on line 140
