I have a completely clean install of WP and GF (both latest versions as of right now) and when I click on "preview" up pops the new window, but I just get the default 404 page. Same thing happens when I try to edit the columns on the entries page: straight to 404.
-- this is a Multisite install. Both the main site and the single existing child site exhibit the same behaviour.
-- I have no other plugins installed except Justin's Members plugin
-- Changing the theme has no effect which is fair enough as these are both on the admin side.
So, anyone have any ideas for this?
Thanks very much!
