Error Code: SEVERE [sys] Cannot load station - javax.baja.xml.XException: Cannot load module hx=hx

Solution

Station fails to load due to missing or corrupted module. The error Cannot load module hx=hx indicates the history extension module cannot be loaded. Solution:

1. Verify all required modules are properly installed and licensed
2. Check module manager for missing or corrupted modules
3. Reinstall the hx (history extension) module if necessary
4. Restore from a known good backup if module corruption is suspected
5. Check module dependencies and ensure all prerequisites are met
