## Troubleshooting

### Language doesn't appear in dropdown

- Verify both `fess_label_[locale].properties` and `fess_message_[locale].properties` exist
- Check that locale code is in `supported.languages` in `fess_config.properties`
- Regenerate Java classes: `mvn dbflute:freegen`
- Rebuild project: `mvn clean package`
- Restart Fess application
