The safe mode allows to prevent the execution of services and tools of this app.
As a system property it allows the administration of Confluence to deactivate this app in the start-up scripts. When users encounter a message that refers to the safe mode, the Confluence server is probably in maintenance mode currently. This may or may not be related to issues with this app. The safe mode can only be deactivated by the administration of the Confluence server.
In case the issue is not resolved, users should check if there are messages of their administration that announced a maintenance period of the Confluence server or get in touch with the Confluence administration.
Details
The system property is typically set on start-up by the Confluence administration via
-Dde.smartics.userscripts.system.safeMode=true
For this version the safe mode prevents the execution of macros and the userscripts provider service of this app. Therefore, if the safe mode is activated, non of the macro executes and no userscripts are provided.

An alternative way to disable apps via the Universal Plugin Manager. While the Safe Mode provided by Userscripts for Confluence only deactivates specific services explicitly, the approach via the Universal Plugin Manager deactivates specific apps (aka plugins) or all apps at once.
