Applicable to:
- Plesk for Linux
Symptoms
When set Nginx Cache size and/or Cache timeout to 0 in Plesk > Domains > example.com > Apache & Nginx Settings > Enable Nginx caching Plesk shows a successful message:
CONFIG_TEXT: Information: The settings were successfully updated.
However, the configuration is broken:
-
The following errors are logged in the file
/var/log/plesk/panel.log:CONFIG_TEXT: DEBUG [panel] Template_Exception: nginx: [emerg] invalid max_size value "max_size=" in /etc/nginx/plesk.conf.d/vhosts/example.com.conf:6

The following error can be shown:
PLESK_ERROR: New configuration files for the Apache web server were not created due to the errors in configuration templates: nginx: [emerg] invalid time value "" in /etc/nginx/plesk.conf.d/vhosts/example.com.conf:91 nginx: configuration file /etc/nginx/nginx.conf test failed
Cause
This is a Plesk bug with ID #PPPM-12428 which is going to be fixed in future Plesk updates.
Resolution
Set a value higher than 0:
-
Connect to the server via SSH
-
Create a list containing the domains with Nginx caching enabled:
# mysql -uadmin -p`cat /etc/psa/.psa.shadow` -D psa -Ne "select d.id, d.name from domains d, dom_param dp, WebServerSettingsParameters ws where d.id = dp.dom_id and dp.param = 'webServerSettingsId' and dp.val = ws.webServerSettingsId and ws.name = 'nginxCacheEnabled' and ws.value = 'true'" > /tmp/domainsList.txt
-
Identify the domains with a non-existing
Cache size:
# echo "-> START"; cat /tmp/domainsList.txt | while read ID DOM; do CHECK=`mysql -uadmin -p$(cat /etc/psa/.psa.shadow) -D psa -Ne "select d.id from domains d, dom_param dp, WebServerSettingsParameters ws where d.id = dp.dom_id and dp.param = 'webServerSettingsId' and dp.val = ws.webServerSettingsId and ws.name = 'nginxCacheSize' and d.id = $ID" | wc -l`; if [ $CHECK -eq 0 ]; then echo -e "--> Domain: $DOM\t ID: $ID"; fi; done; echo "-> FINISH"
Cache timeout:
# echo "-> START"; cat /tmp/domainsList.txt | while read ID DOM; do CHECK=`mysql -uadmin -p$(cat /etc/psa/.psa.shadow) -D psa -Ne "select d.id from domains d, dom_param dp, WebServerSettingsParameters ws where d.id = dp.dom_id and dp.param = 'webServerSettingsId' and dp.val = ws.webServerSettingsId and ws.name = 'nginxCacheTimeout' and d.id = $ID" | wc -l`; if [ $CHECK -eq 0 ]; then echo -e "--> Domain: $DOM\t ID: $ID"; fi; done; echo "-> FINISH"
Note: The previous command will show an output as follows:
CONFIG_TEXT: -> START
--> Domain: example.com ID: 3
-> FINISH -
Go to Domains > example.com > Apache & Nginx Settings > Enable Nginx caching
-
Set a value higher than
0for Cache size/Cache timeout -
Click the OK button
Note: Repeat steps 5-7 for all domains from the list that was fetched on step 3.

Hello, unfortunately this solution did not solve the problem for me.
This is what i obtain on step 5 - 7: (the same happens if i clear the contents of "Additional nginx directives" field)
Hello Gianluca
According to the error message, the configuration file
contains an invalid value for "max_size".
Try the default one "max_size=67108864"
The issue isn't connected with this article. The reported error just blocks any changes due to incorrect Nginx configuration.
