Diagnosis
Check if there is a file named directory.properties under crowd_home
Cause
If you have moved the directory.properties to your <crowd_home> directory, then you have accidentally enabled the file-based directory configuration.
The existence of this file directly in the <crowd_home> directory (regardless of its contents) enables the feature, which triggered this bug: CWD-3001 - Getting issue details... STATUS
Resolution
Remove the file directory.properties from the <crowd_home> directory
Restart crowd
Having the file directory.properties in <crowd_home>/backup/ is fine and will not trigger this bug.
