- Plesk for Linux
Subscription settings are not synced between a Management Node and Service Nodes, if the Addendio - Wordpress Plugins and Themes extension is installed and enabled on the Service Node.
This is a Plesk bug with ID PPPM-6880, which is planned to be fixed in future product updates.
As a workaround disable the extension:
In Plesk go to Extensions > My Extensions.
Select the Addendio extension and click Disable.
