When visiting as admin a user's account I click on the
Session > Return to accounts

And when I am back to /admin when I click Logout it doesn't log me out.
It just keeping me in the same accounts page.
If I go to another page as admin in /admin/ like
Hosts or Status and press logout it will again redirect me to accounts page and not logout.

Are you running the latest version ?? /usr/local/centovacast/sbin/update Sometimes they don't post updates but there is an update on the server to be downloaded.

This bug has already been fixed.  djduck is correct about our releases (I went into more detail in the last paragraph of this post) but regardless of that, I believe this fix was in the announced v3.0.1 release anyway.  Please upgrade.
