WP Plugin Upgrades fail

I get this error on all of my various blogs on dreamhost when trying to upgrade any WP plugins:

[font=Courier]Downloading update from http://downloads.wordpress.org/plugin/akismet.2.5.2.zip…

Unpacking the update…

Could not create directory. /home/xyz/xyz.com/wp-content/upgrade/akismet.tmp/akismet[/font]

Any idea how to resolve this?

I’ve tried marking the entire chain of directories as 777 - that doesn’t help.

Do you actually have an “upgrade” directory under wp-content? That needs to exist. If you do have /upgrade, then create akismet.tmp as well and see what happens.

755 should be sufficient (and safe), or even go so far as 775, but 777 should not be used.

Yes… I’ve tried creating that directory path manually - that succeeds.

Yet the WP plugin upgrading system always fails.

How puzzling.
