Problem override of AdminOrdersController class after migration PrestaShop 1.6.0.11 to 1.6.1.6

[Rihab002]

Hello,

 

I added two columns to the list of commands in the backoffice carrier and city (I created an override of the __construct () method  of controller AdminOrderController.php )

Everything works well.

 

 After the migration of PrestaShop( 1.6.0.11  to 1.6.1.6) the two columns don't appear in the backoffice command list.

I emptied the cache  nothing changed.

I deleted the file class_index.php, both columns have appeared in the command list , but after some time they disappear.

 

Can you please help me to solve this problem?

can you share which way you used to migrate Prestashop to Prestashop?

If you did it manually or hire developers to migrate, it is usually that errors can happen such as loosing image, information, or disappearing control panel or the error like you. I think you can try the other way, such as using an available Prestashop upgrade tool. These tools are coded and tested carefully and used popularly by lots of merchants so they are quite prestigious. Some of them such as Cart to Cart or LitExtension- 2 big migration providers now.
