I just updated to WordPress version 3.1.2. When I'm working in the administration application I'm periodically getting kicked out to the log-in screen (wp-login.php?).
For instance, I'm editing an entry. I click on "Preview." I go there fine. But when I do a refresh, it tells me "You do not have permission to preview drafts." I return to my editing window. I click on "Preview". I'm taken to the administration log-in screen. I log in and I'm at the dashboard. I click on "View" for the post I want to preview. At the top I have a menu option of "Editing Post" I click on that -- I go to the log-in screen.
Another example. I'm editing an entry. I click on the plug-in icon. I'm kicked out to the admin log-in screen.
Any ideas what's up?
