Hello please tell me why is my XOOPS 2.2 (the newest one) keep telling me instead of database successfully updated - invalid session?!

i have to update the module in which this is going on (it goes on in all...) and then sometimes work and sometimes don't... IT IS LIKE IT IS UNSTABLE :)

it does this to me on localhost and on the internet, so don't tell check out your host or update core ... i did that!

i'm using autologin hack, and some modules with no hacks.
and i really like 2.2.

edit: ok maybe i can tell that happens when i login with two different users from the same computer with diffrent browsers...

tnx, bye
