🐛 Common Issues & Troubleshooting

1. Cannot Delete Area

Issue: "لا يمكن حذف هذه الشركة لوجود عملاء مرتبطين بها"

Cause: Customers are assigned to this area

Solution: Reassign customers to different areas first

2. Shipping Cost Not Updating

Issue: Shipping cost changes not reflected

Cause: Ajax request failing or validation error

Solution: Check numeric format and user permissions

3. Associated Tag Not Displaying

Issue: Tag names not showing in area list

Cause: Missing or deleted associated tag

Solution: Verify tag exists and is not marked as deleted
