Restrict the ability to create a subspace
Problem
How is it possible to restrict the ability to create a subspace to Global Administrators only?
Solution
You can deactivate the links to create a subspace or to change the parent space of a subspace outside the administration by disabling the modules of the Subspace plugin:
Add Space (subspace.addspace)
Change Parent Space (subspace.change.parentspace)
Add Space (subspace.addspace.tools)
Change Parent Space (subspace.change.parentspace.tools)
To disable these modules navigate to: "Confluence Administration" => "Manage add-ons", click on "SubSpace plugin" and click on the link "17 of 18 modules are enabled" (on the right side). Now you can disable the four modules.
Please not, the URLs: "<Confluence_URL>/communardo_plugins/createsubspace/createspacehierarchy-start.action?key=<Space_Key>" and "<Confluence_URL>/communardo_plugins/createsubspace/changeparentspace-start.action?key=<Space_Key>" are still available via direct URL access.
