Does anyone know a simple way to make (relatively old) Fantastico-installed WP sites work with the new built-in auto-upgrading functions?
I believe there's some kind of issue with user permissions. On some sites I look after, there seems to be a problem with WP connecting successfully via FTP; that may or may not be related.
I don't mind too much about updating WP Core via Fantastico; I don't usually mind waiting the couple of days it seems to take for Fantastico to start offering the update. But it would be very handy indeed for plugin management, which Fantastico can't help with.
