Empty Space Directory page after upgrading Confluence
After upgrading to Confluence version 3.5.x, Space Directory page is empty.
This is most likely caused by customised Global Layout when Confluence was still in version prior to 3.5. Run the following query to confirm this:
SELECT * FROM DECORATOR WHERE DECORATORNAME = "decorators/global.vmd";
If this returns anything, it means that there has been some customisation made to your Global Layout, which is potentially causing the Space Directory to be unpopulated.
Reset or fix the custom Global Layout. Please see the Modifying the global template or layout section of Customising the Confluence Dashboard for details on how to do this.
