AdminCategories Problem

[Tom Jamon]

Hi,

 

I got a problem when i try to reorder the categories in the admin panel. Cf Screenshot.

 

I got a 200 (Ok message) like if there is no error but when i reload the page (directly from the refresh link from Prestashop or simply with the browser), changements haven't been applied.. (sometime it's work, like 1/20 times)

 

In the database, i can see that the position_id is wrong. 

For example on 3 elements : 0,1,3.

 

I'm using Prestashop 1.6.0.14

I haven't overrided any Classes or Controller yet, it's the classic installation of Prestashop.

 

Thanks for helping, i hope my english is understable.

Tom.
