Confluence 5.2 has reached end of life
Check out the [latest version] of the documentation
In Confluence, the ancestor table defines what pages are ancestors or descendants of other pages (which can be used by search restrictions with the ancestorids restriction). Occasionally, the ancestor table will become out of sync. When this happens, you can rebuild the table to restore everything to normal.
Access this URL:
http://yoursite/admin/permissions/pagepermsadmin.action
After rebuilding the ancestor table, you'll need to flush the "Inherited Content Permissions" cache in Cache Statistics, otherwise the inherited permissions may not be applied immediately to all pages. You may also need to rebuild the content index so that the permissions take effect in search results.
