I used the Magento2 version: 2.1.0

In the admin panel when I want to go to generating Shipment I see the details of the order but Save Shipment and Product Details are missing.

And when I checked the system.log I see below error message:

main.CRITICAL: Renderer for type "simple" does not exist.

see the attached screenshot.

enter image description here

If anyone have already solved this issue, please help me to fixed this issue.

Thanks in Advance!

I got the solution for this.

I have installed the Aitoc_PreOrders and in this extension, I see the below error log:

Warning: unserialize() expects parameter 1 to be string, array given in /app/code/Aitoc/PreOrders/view/adminhtml/templates/items/column/name.phtml on line 24

I just solve it and its working.
