I tried to use the "upgrade automatically" option in admin and it didn't work. I got an error message while it was unpacking the files. Something about not being able to rename a class in class-pclzip.php. Sorry, I didn't save the actual message.
Then I tried WPAU but it says that my installation is up to date.
What's up with that?
I have done a manual upgrade (once) for a client, but I really prefer to use WPAU.
Thanks
