Applicable to:
- Plesk for Linux
Symptoms
-
Unable to upload a file in Wordpress > example.com > Log in > Media > Add New with the following error
Missing temporary directory
OR
Missing a temporary folder
-
There are the following records in
/var/www/vhosts/system/example.com/logs/error_logfile:AH01071: Got error 'PHP message: PHP Warning: File upload error - unable to create a temporary file in Unknown on line 0\n', referer: https://example.com/wp-admin/upload.php
-
By default PHP-FPM service has PrivateTmp enabled:
# systemctl cat plesk-php72-fpm.service | grep PrivateTmp
PrivateTmp=trueNote: the PHP version can be identified in Domains > example.com > PHP Settings.
-
PrivateTmp=truemeans that uploaded files uses the following folder:/tmp/systemd-private-a843c1c414a649b6a153d621c2607c9e-plesk-php72-fpm.service-UuymOU/tmp/
Cause
/tmp folder has been cleaned up recently with rm -rf /tmp/*. The temporary folder can also be cleaned by 3rd party tools that delete temporary files such as tmpreaper package.
Cleaning up /tmp folder resulted in the fact that /tmp for the PHP-FPM does not exist.
Resolution
Warning: If there is a 3rd party tool software deleting the temporary files, such as tmpreaper package, make sure to configure it properly or uninstall it from the system to avoid any conflict with Plesk and other services
-
Identify the PHP version used by the domain in Domains > example.com > PHP Settings:
-
Restart the PHP service in Tools & Settings > Services Management by clicking the yellow restart icon. This will recreate the temporary folder:

Hi,
I have exactly this problem, that Wordpress complains about an missing temp folder and I have tried to do the workaround as described here
https://www.wpbeginner.com/wp-tutorials/how-to-fix-missing-a-temporary-folder-error-in-wordpress/
but doesn't solve the problem. Since I have this issue on different subdomains, I believe the issue is somewhere on the Plesk/Server side.
I am not an IT-expert and for me the above text is too cryptic. What does it mean to /how do I restart the PHP service? I can log-into Plesk Obsidian and I see the "PHP settings (v7.3.20)" but there is no possibility to restart it.
Can you please provide more information. Thank you.
Hi bjoern.gerlach,
You can restart the PHP service corresponding to that domain in Plesk > Tools & Settings > Services Management > restart the service on the right-hand side of the PHP version
The step described in the article refers to restarting the service via SSH in the Linux console.
Dear Nelson,
thank you so much for your response. I guess I found the "Services Management" page under the heading "Server Management":
Interestingly enough, on this Service page I was not able to find any reference to PHP:
Does this explain my problem? Any thoughts what to do?
I appreciate your support. Thank you,
Björn
Hello bjoern.gerlach
Indeed, this doesn't look right.
Please, make sure, that PHP versions in question are installed, this article should help you.
If installing missing PHP handler won't help, submit a support request, additional investigation will be required.
Hi Ivan,
thanks a lot for your response. I had updated already the PHP version as you described and this indeed solved my problem.
Best,
Björn
Hello bjoern.gerlach
Glad to hear that it's resolved now =)
I have this problem frequently and when the service has been restarted all working well.
But then the problem return, there is any method for fix permanently? :/
Thanks for all
