Hey,guys, i met a logout problem in silverstripe 2.4 these days.
If the website is viewing in both front and backend, and did some operations on backend eg.(change and save and publish), a pop up window says please logout and try again...but i am the admin and have the highest permission..
anyone have any ideas?

Running firebug it shows the error:
http://mydomain/admin/getitem?ID=111&ajax=1 403 Foridden

not too sure what kind problem is that?!
cookies or session ? or something else?!

Hey.Willr, thanks for replying.
i have been logged in for a while, but as long as i click and refresh some frontend page, then go back to admin area(backend), select page in left hand site-tree view, it shows the strange problem.
Have tested some other site i have built in 2.4, but only this one seems little bit odds.

i tried to comment out the permission check code in the Leftandmain.php for admin/getitem?ID=111&ajax=1
   //   if($record && !$record->canView()) return Security::permissionFailure($this);
Seems the problem still remaining.

Any thoughts on that?!

cheers.
Alex
