When I view it in FF even while logged out I see the facebook login button, recent threads and forum stats etc in the sidebar. When I view it in IE I only see the Twitter block and "Sign up Now"
When I view the forum while logged out in IE, I don't see the FaceBook login button, but I see everything else I should (I've tried using the default theme and the same thing happens)
I have no idea what's causing this. The only thign I've done to the templates besides color changes is add the Facebook login by following this thread http://xenforo.com/community/threads/login-with-fb-into-sidebar.11777/#post-156265
http://hahanozugzug.com is my site.
UPDATE: I got these issues sorted, I guess it was permissions.
