“Missing a Temporary Folder” Error in WordPress

Recently, one of our clients was seeing “Missing a Temporary Folder” on his WordPress, and due to this error, he was unable to upload images, update themes, and plugins.

Missing a Temporary Folder

Solution 1.

The “Missing a Temporary Folder” error can be the result of incorrect PHP settings on your CloudLinux based cPanel hosting environment. One of those settings includes the tmp folder existence in /home/user/tmp. Also, make sure the quota limit of the account is not exceeded.

Solution 2.

If everything seems good but still you’re getting a “Missing a Temporary Folder” error, then the problem can be due to if the user is not enabled correctly in CageFS. Upon checking, the user might be appearing in CageFS, but it’s not enabled properly.

To fix this, remove the user from CageFS and re-add it. This can be done either via WHM or via SSH.

 Using WHM

  1. Log into your WHM panel
  2. Go to Plugins >> CageFS
  3. Select the user you want to remove from the CageFS and click on “>>”.
  4. Once done click on “Update CageFS skeleton”

Now you have successfully disabled CageFS for that specific user. To re-enable a user in CageFS select the user from “Disabled users” and click on “<<“. Once you’ve done then click on “Update CageFS skeleton”.

Using SSH:

You can enable or disable the user from CageFS by using the following commands:

#/usr/sbin/cagefsctl --disable $username 
#/usr/sbin/cagefsctl --enable $username 
#/usr/sbin/cagefsctl --force-update

You can also remount the CagefS:

#/usr/sbin/cagefsctl --remount-all 
#/usr/sbin/cagefsctl --force-update
