I just upgraded my wordpress to 2.2 version and this error it's showing in dashboard:
You don't have permission to access /wp-admin/index-extra.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
I can't see incoming links or news, everything it's with this error.
I saw a topic opened with this but doesn't help, it says something about k2 themes that I think I'm not using.
Any help will be really apreciated.
