I've seed this topic discussed but most of the threads are from a couple years ago.
I started getting this error a couple weeks ago:
143.JPG” has failed to upload due to an error Missing a temporary folder.
I've tried just about every fix written about here at wordpress support.
I've spent many hours on the phone with godaddy and they haven't been able to help. Tried complete uninstall of my site and clean install.
On 8/4 godaddy upgraded my acct...so you'd think there's something there but they checked everything.
