Recently i got the error
“missing A Temporary Folder.” After Uploading A File
After digging lots of sites, i was unable to fix the problem.
Maximum sites offer solution like change php.ini etc. but changing configuration file and using shell command can be avoided by a simple trick.
Go to Plugins Tab in wordpress after Login.
And thus your problem solved.
you want to use that editor then use or Simply Deactivate but don’t uninstall.
