Check the layer that owns the failure
- Component missing: license, dependency, or Component Availability
- Component renders empty: current context, native data, privacy, or audience policy
- Mutation fails: nonce, login state, permission, membership, or Community Engine rule
- Route is wrong: mapping, template publication, canonical BuddyPress URL, or cache
- Forum unavailable: activate BuddyBoss Forum Discussions or bbPress
Safe isolation sequence
- Reproduce on the canonical route.
- Check as administrator and ordinary member.
- Disable page caching for the route.
- Confirm the native BuddyPress object exists.
- Review Community Engine and component visibility.
- Capture the REST status and error code.
