I am new to Opencart ! I am facing some problem here , i am going to explain what it is ..! client had setup some logic that if product weight is more than 20kg shipping will free else shipping cost is applicable .
the problem is when tired 'ESTIMATE SHIPPING & TAXES' till 20 kg its showing fine but after 20 kg its showing error as 'Warning: No Shipping options are available. Please contact us for assistance!' instead of showing free shipping
i am not getting where i am wrong ! please anyone suggest me where i am wrong or what needs to be done to remove this error !
Well, it seems you have just no setup free shipping.
so while you have less than 20 kg, the paid shipping is active and so you are good.
but once is over 20 kg, the paid shipping is removed, leaving you with no shipping options. you still need to set up a shipping method that would deal with weight over and including 20 kg orders.
I would be able to help further if I knew exactly which shipping methods you have active but I can see from the screen shots that free shipping is actually off
