## 🚨 Troubleshooting

### Issue: Balances showing KES 0.00
- **Cause:** No transactions posted to GL
- **Solution:** Ensure loan disbursements/repayments are creating journal entries
- **Check:** `/admin/` → accounting → General Ledger

### Issue: Account not found
- **Cause:** Account code doesn't exist
- **Solution:** Verify account code in Chart of Accounts
- **Check:** Account might be inactive

### Issue: Click badge nothing happens
- **Cause:** JavaScript error or account doesn't exist
- **Solution:** Check browser console for errors
- **Check:** Ensure account code matches exactly

### Issue: Export shows "No data"
- **Cause:** No transactions in selected period
- **Solution:** Adjust date range or clear filters
- **Check:** Try "All Time" date range
