Warning: Division by zero in /includes/classes/shipping.php on line 94

on my website when customer tries to check out, two errors comes:

Warning: Division by zero in /includes/classes/shipping.php on line 94

Warning: Division by zero in /includes/classes/shipping.php on line 95

this is what is in my file on 94 and 95

93 if ($shipping_weight > SHIPPING_MAX_WEIGHT) { // Split into many boxes
94 $shipping_num_boxes = 0; ceil($shipping_weight/SHIPPING_MAX_WEIGHT);
95 $shipping_weight = 0; $shipping_weight/$shipping_num_boxes;
96 }

Please let me know what i'm doing wrong?

Thanks

What do you have for the settings in Admin> Configuration> Shipping and Packaging?

If your Maximum weight is 0 - you can not ship anything larger than that ...

what should i put then?

i updated to 1. and it works great now.

i also have another problem:

I have a floating glass cart on my website and customers are complaining that when they add items to the cart and then go help customers or they go to lunch time and when they come back after 1 hour, cart goes empty. please help. i need my session to be like like 1 day or something.

i am still getting that same message:

Your maximum shipping weight needs to be a much larger number - it is usually something like 50 to 75 pounds - Check with your shipping company to find out what the largest single box they will accept is.

Your other issue with timing out is off topic for this thread.
