From the help files it says:
Upgrading from any previous WordPress to 2.7:
- Delete your old WP files, saving ones you've modified.
- Upload the new files.
- Point your browser to /wp-admin/upgrade.php.
Well, I did this but I could only get to the front page. When I clicked login it did not ask me to update, but I got page not found.
I left my config.php in there, and figured I could replace the altered css files later since I'm just using the plain Kubrick.
Could it be that I changed the wrapper from wordpress to another word?
I used the correct word in the URL.
