Tried deactivating all plugins... attempted automatic update of Wordpress Stats plugin...
Downloading update from http://downloads.wordpress.org/plugin/stats.1.7.3.zip…
Unpacking the update…
Could not create directory. /public_html
I can guarantee you that the automated upgrader does not deactivate plugins before the upgrade. The plugins will remain active unless manually deactivated prior to the upgrade.
I was referring to the Wordpress Automatic Upgrade
plugin, which does disable plugins, that worked well in the past but does not work currently. I have tried upgrading using this plugin and using the built-in upgrade function with no success.
The new, built-in automatic upgrade function does not
deactivate plugins... you are correct.
Just tried upgrading another blog (3.0 -> 3.0.1) using the built-in upgrader, all plugins disabled:
Downloading update from http://wordpress.org/wordpress-3.0.1.zip.
Unpacking the update.
Verifying the unpacked files…
Installing the latest version…
Could not copy file: /public_html/blog/wp-admin/css/colors-classic.dev.css
This is very typical of my failures, but with differing file copy failures.
