Cause
Product issue:
-
#PPPM-12428 "Improved the nginx cache size validation."
Fixed in:- Plesk Obsidian 27 October 2020 (Linux)
Resolution
Workaround
If update is not possible for some reason you may try the following
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.
