Fix for Auto-update on WordPress 2.8 and ‘Could not create Temporary file’

I’ve spent the better part of the last two days trying to figure out why my wordpress would no longer auto-update files without asking for FTP information, and even then, failing when trying to update. The failure message I was receiving is: Download failed.: Could not create Temporary file

I finally found a solution on Keith Garner’s Blog.

The main article, which fixes the auto-update problem, can be found here

It also links to a second article, which discusses the temporary file failure problem.

Enjoy!
