I'm getting "Download failed. Failed to write request to temporary file." when I try to download plugins, and the plugins (that were working) are now unable to write what they need to (namely a caching plugin.).
I'm running a CentOS on a VPS with Apache, etc and have suPHP installed. Permissions are set properly (644 and 755) and ownership of the files is under the user.
The issue has started since I added another user to my box (using centos webpanel FWIW).
Also, just verified that the other use CAN install plugins on its wordpress installation.
How did adding a user knockout my existing user?
So far none of the threads on this have solved my problem.
Edit: Also tried setting temp dir to wp-content and 777'd wp-content. Still no luck. Even with Apache restarts. I'm grasping at straws.
Could this be an issue with vhosts or suphp config?
