Re: WordPress Upgrade Failed, Download Failed, Could not create Temporary file
This problem can be caused by over-securing your WordPress installation – not a bad thing! Here is a quick way to get the upgrade working.
- CHMOD 777 the /wp-content folder
- Perform the WordPress Upgrade
- CHMOD 755 the /wp-content folder
If this fails, make sure you have the folder /wp-content/upgrade created.
Your WordPress should now upgrade successfully.
