I just upgraded my WordPress to 3.0 from that last version.
It's working OK, but if I click on 'posts' (edit.php) or 'media' (upload.php), I get a 'page not found error'.
I have re-installed wordpress 3.0 as a clean install, instead of an upgrade, and have deactivated all plugins - still same problem?
Can anyone help?
Thanks in advance,
