problème de login avec glpi sous LAMP

bonjour,

suite à une erreur de manipulation : apt-get dist-upgrade
J'ai des soucis sur mon serveur sous LAMP
j'héberge Egroupware / Squirrelmail / Qmailadmin / GLPI
et depuis cette erreur de manip je n'arrive plus a me logguer sous glpi, alors que les autres fonctionnent parfaitement.

j'atterri sur une page vierge

et j'ai eu ce genre de message dans le syslog :
