I have WP3 alpha installed and working nicely except one thing: when I try and edit the site settings (/wp-admin/ms-sites.php?action=editblog&id=2) I get a 400 Error whenever I press the "Update Options" Button.
I notice that the page that gives the 400 Error is "wp-admin/ms-edit.php?action=updateblog" there is no "&id=2" on the end. If I add "&id=2" to the address and resubmit, I get a page with a box containing the text "Are you sure you want to do this?" - but there are no buttons to go on from there.
Any suggestions as to why I'm getting this error?
