- Confluence user base is unchanged but has changed locations. For example, reverting from Crowd or JIRA to Internal User Management.
- Confluence index has been corrupted
Resolution
Rebuild the Confluence index from scratch
These errors will also dissipate as on a per user basis as the index updates itself but rebuilding it from scratch will ensure they are all corrected all at once.
