Ocs 2.2 Stuck when i try to create a new user or modify admin password.

Hi, i recently installed the lastest OCS Inventory Server (2.2). But when i try to modify the admin password or create a teledeploy user and click to create him it gets stuck and i dont  get any error message or something.

I try to do the same on DEBUG mode and i have "Wait" on config menu below DEBUG.

I im using Ubuntu 12.04.   Thanks.
