While Tag Groups Premium tries to keep track of all changes to posts, tags, groups or taxonomies, it may occasionally happen that the data becomes inconsistent. In that you can run several maintenance scripts that execute the following tasks:
- Remove from post meta non-existing groups, non-existing terms, terms in wrong groups and groups without tags.
- Remove from term meta non-existing groups.
- Empty the transient cache and schedules the rebuilding of post counts.
You find the “Maintenance” button in the Settings, under the “Support” tab.
