Hi,
I have just tried to do a manual upgrade from 2.9.2 to 3.0 (attempting to do an automatic upgrade returned a fatal error: not enough free memory).
I followed all the instructions for the manual upgrade but now i cannot access the admin page for the current install.
My blog page is: http://www.grumbles.com.au/Forum
and my wordpress installation is at: http://www.grumbles.com.au/grumbles/
Would it be because of the different URL's?
