PrestaShop 1.7.8.5 - The product does not appear in the shopping cart.

[User12345678]

Hello,

After clicking buy, the product does not appear in the shopping cart.

I use Standart installed theme and shopping cart.

 

I tried to disable / uninstall / install the module, clear the cache, change browsers. Does not work.

 

Before the problem occurred: Features and value were created. Also assigned to products and a filter created by features.

Maybe somewhere the code needs to be changed?

When MySQL opens, it shows the items in the cart.

Now run debug mode on shopping cart:

https://www.xxxxx.xxx/en/module/ps_shoppingcart/ajax?action=add-to-cart

And get this:

Whoops, looks like something went wrong.

(1/1) ContextErrorException

Notice: Trying to access array offset on value of type null
