I am getting the much maligned Upgrade fail message:
Downloading update from http://downloads.wordpress.org/plugin/akismet.2.5.1.zip…
Unpacking the update…
Could not copy file
This happens for every plugin and core upgrade. I've tried all the usual things like deleting the upgrade folder and changing permissions.
I feel silly posting this but I'm at a loss. I am the server admin so I have full access but I'm not sure how to correct this. I also know that I was at one time able to do automatic upgrades but can't for the life of me think of anything that I've changed that would cause this.
Any guidance would be greatly appreciated.
