Product Combination bulk not showing any combination in BO

[cortsenc]

Hello,

I had Prestashop 1.7.5.0 and I upgrade to 1.7.6.5 without problems. Now, when in BO I go to Product > Combination tab, I don't see any combinations in any Product. But I can see from de FO.

Symfony debugger didn't show any error, but when I use DevTools, I compared the XHR calls, and show me some missing calls from 1.7.6.5:

Both Prestashops, 1.7.5.0 and upgraded 1.7.6.5:
index.php/sell/catalog/products/attributes/get-all?_token=***
index.php/sell/catalog/products/specific-prices/list/4075?_token=***

Only in 1.7.5.0:
index.php/sell/catalog/products/attributes/form-images/4075?_token=***
index.php/sell/catalog/products/combinations/form/61010?_token=***

Does anybody now where the third and forth call comes from (I supose JavaScript file), and where I can put a breakpoint to debug why this calls are never called?

Thanks,

Note: I paste here both screenshots with web inspector:

Hi,

Whitch   PHP    version    is  enabled  in your  server?

I had PHP 7.0 when we migrated Prestashop to 1.7.6.5 but now I migrate PHP to PHP 7.2

PHP   7.2   is   fine.

Did  you enable  debug   mode?

 

Yes, but there weren't any errors. It just there are GET AJAX request missing (only 3), and If I knew where they had suposed to be called, I could put a breakpoint and debug which variable is missing or table problems...

 

 

 

It seems that is still loading. It has the list of data-ids-product-attribute but still don't load it:
