My plugins won't update. I get
Downloading update from http://downloads.wordpress.org/plugin/akismet.2.5.1.zip…
and then nothing else.
I was hoping that updating to 3.0.4 would fix it, but it hasn't.
I think I'll try updating them manually via FTP. Do I just overwrite the old plugin files? Should I deactivate each plugin first? And will my plugin settings be retained?
