## ❓ FAQ

### Q: Is this safe to deploy?
**A**: Yes. ✅ This is purely defensive code - no business logic changes. Low risk fix.

### Q: Do I need to restart the application?
**A**: Yes. Either restart IIS or touch web.config to trigger app pool recycle.

### Q: Will this break anything?
**A**: No. Code handles all failure modes gracefully by returning defaults.

### Q: How long does deployment take?
**A**: ~15 minutes (stop IIS, copy DLL, restart, verify)

### Q: Do I need to run database scripts?
**A**: Already done (SQM_Update_116 and SQM_Update_117 executed). Backups created.

### Q: What if something goes wrong?
**A**: Restore previous PageSettings.dll from backup, restart IIS, clear temp files.

### Q: Will pages load slower?
**A**: Negligible impact. Added null checks have minimal performance cost.

### Q: Does this fix the theme rendering issue?
**A**: Yes. The fix prevents the exception during theme loading in mojoThemeVirtualFile.
