ocs inventory 2.2 change web gui admin password

hi,

I've updated from ocs inventory 2.1 to 2.2 today, update went well, but now I can't change the Web GUI admin password if I go to "My Account" and type in my new one in the "Password" field.. then the Web GUI simply stays white, and the admin password is not changed.

is there any other way to change the admin Web GUI password?

best regards

martin
