Missing a temporary folder. WordPress error can be caused for multiple reasons:
- Inodes/Disk usage is over quota and new files can’t be created
- CageFS is blocking requests/permissions
- A custom upload path is set in the wp-config.php file
- Required extensions are not installed or disabled
- Folder wp-content/uploads is missing or have wrong permissions
How to fix this error:
1. Enable required extensions
Check if required extensions are enabled in Tools > Site Health:
If they are not, enable them from cPanel > PHP Selector
2. Check wp-config.php for WP_TEMP_DIR
Check if a custom path for file uploads is set in wp-config.php
Check wp-config file for “WP_TEMP_DIR” and if it is set, either remove the line or make sure that directory exists and is writeable.
3. Restart CageFS
CageFS is a virtualized, per-user file system that uniquely encapsulates each customer, preventing users from seeing each other and viewing sensitive information.
From time to time, CageFS is known to cause troubles and the solution there is pretty straightforward> Ask your hosting provider to restart CageFS for your account.
If you have a VPS/DEDICATED server with root-level access, you can disable/enable cageFS from the terminal with the commands:
/usr/sbin/cagefsctl --disable $username
/usr/sbin/cagefsctl --enable $usernameIf you have any other solutions that fixed this “Missing a temporary folder.” WordPress error for you, please share them in the comments. 🙂
