Forum should I be alarmed?

[محروم.كوم]

Hi,
I just connected to my forum as admin and I noticed that all new posts were considered "read" why they shouldn't. I changed my password and when I tried to log out I got this error message:


An error occurred while attempting to log you out. Click here to log out.


I clicked; the cockies were cleared and then I relogged with my new password.

Strange as this might be, I am reluctant to believed that someone should have hacked my administrator account. Nevertheless, can I trace the last activity of my admin account? Stuff like used ip or the last actions made by the account?

thanks __DEFINE_LIKE_SHARE__
