Yep… bus after 5 hours of test i find out that the Sociable plugin its ok.. if u try to disable all plugins that create an extra “windows” at the admin panel, such as Next Gallery, Polls, Security Scann ecc, everything its ok… the problem is that the new wordpress 2.8 have new code in css and javascript.. and plugins wich have to do with dashboard create problems… we have only to wait…
P.S Super Cache creates sometimes problems too…
Headspace2 creates big problems ??
